In this task, you must classify if a given review is positive/negative, indicating your answer as P or N.

Example Input: by the time dennis quaid , the ostensible star of switchback , makes his first appearance at about the 22-minute mark , you may find yourself wondering why he bothered .
after all , writer / director jeb stuart has already set up a fairly promising pair of parallel story lines .
the first finds amarillo , texas sheriff buck olmstead ( r . lee ermey ) facing a hotly - contested election battle just as a brutal double homicide is discovered at a motel in his jurisdiction .
as olmstead begins his investigation , we also meet the two men who come to be our prime suspects .
lane dixon ( jared leto ) is an enigmatic young hitchhiker ; bob goodall ( danny glover ) is the jovial motorist who offers lane a ride from texas to his utah destination .
all the necessary conflicts seem to be in place -- the internal struggle of olmstead over the clash between good politics and good police work , and the external struggle as one of the two travelers eventually becomes villain to the other 's protagonist .
but then quaid shows up as grimly determined fbi agent frank lacrosse .
lacrosse is certain that the amarillo murders are the work of a serial killer he has been tracking for nearly two years .
he 's not supposed to be tracking him any more -- according to the bureau , they 've got their man -- but lacrosse has a very important reason for believing otherwise .
two months earlier , lacrosse 's own son was kidnapped by the killer , and the boy has yet to turn up anywhere .
lacrosse knows his killer 's work , and he knows that the man is still out there somewhere trying to continue their game .
it would n't be fair to reduce everything that 's wrong with switchback to quaid 's presence , but it 's a pretty good place to start .
there 's a reason lacrosse feels like an intruder in the narrative instead of its vital center :
as a dramatic actor , dennis quaid possesses exactly one facial expression and one vocal intonation .
we can tell lacrosse is determined because his face is a perpetual tight - jawed , sourpuss pucker ; we can tell he 's grim because every word comes out in an eastwood - esque rasp .
a more flexible performer might have given weight to the character , pulling the audience into his haunted intensity , making switchback _ his _ film .
quaid
merely looks annoyed and slightly constipated .
it 's tough to become emotionally invested in a character 's turmoil when it looks like all he really needs is a big bowl of bran flakes .
even without quaid , it does n't appear that switchback would have stayed on course .
the early scenes between leto and glover have a lively energy , building our curiosity over which man -- the taciturn kid or his gregarious benefactor -- is the real threat .
unfortunately , stuart tips his hand far too early in the game , both through the pitch of the individual performances and the facts he chooses to reveal .
once the mystery of the killer 's identity is dispatched , the interaction between leto and glover becomes stale and predictable
.
in fact , " stale and predictable " describes the direction that switchback takes in general , falling back on far - too - common hollywood devices like cats jumping out of nowhere , a climactic fistfight on board a freight train , and edgy law enforcement agents .
it 's too bad stuart was n't willing to spend more time with sheriff olmstead , far and away the most interesting and appealing character in the film .
played with atypical restraint by r .
lee ermey
, he 's a wonderful , unconventional hero who seems genuinely comfortable accepting the consequences of acting on his convictions .
a film focusing on the olmstead would have signaled a film - maker willing to take a few risks with his casting and story - telling .
instead , stuart places his trust in a " name " star who ca n't carry the material .
maybe next time he 'll throw away that one crucial page in the script , the one where the grimly determined fbi agent wanders onto the scene to muck up a perfectly good story .
Example Output: N

Example Input: " saving silverman " is a good example of a good comedy gone bad
.
as a love story it is good , however as a comedy
it falls flat on it 's face
.
i think throughout the short 90 minutes i laughed a total of seven times . . .
and those were just chuckles at the most !
the movie does n't have the oomph to make it a great movie , and does n't have the script to make it a funny movie .
wayne lefessier ( steven zahn ) ,
j .
d .
mcnugent
( jack black ) , and darren silverman ( jason biggs ) have grown up all their lives together , they have been best friends forever and vow to stay close till the end .
while in a bar after doing a show with their band , based on their love of neil diamond , darren meets a young woman named judith ( amanda peet ) whom he instantly falls for .
wayne and j .
d . however think differently and when judith tells darren that he can never see his friends again
, it 's up to wayne and
j . d . to try and begin saving silverman .
the performances are topnotch and
surprisingly , they are what keep the movie afloat .
jason biggs right off the flop " loser " does an ok job playing silverman , but he is stale and flat at times .
steve zahn is perfect in the role of wayne lefessier , and even though the movie is about silverman , lefessier is really the main character and the narrator of the movie itself .
jack black is well jack black , and he does an all right job as j .
d .
but he is n't as funny as he has been in the past .
amanda peet plays the ultimate bitch as judith , and neil diamond plays neil diamond ( he 's better at singing than acting ) .
anyway the performances in the film are good , but it 's too bad the script is n't .
speaking of script , hank nelkan 's choppy script is not only badly written , but not funny enough even for an episode of sesame street .
the trailer for the movie , as with most movies gives away everything that happens in the movie , especially the funniest parts .
somewhere " saving silverman " was meant to be a good movie , and it could have been , but alas in the end it was n't .
dennis dugan 's direction is all right , he adds a few directorial touches here
and there , nothing special being a simple comedy .
" saving silverman " is a perfectly bad movie in more ways than one .
it has a great cast , a good director and a sweet story .
. .
it 's just too bad
it has a bad script and is all together a bad movie .

Example Input: deserves recognition for : achieving the near - impossible task of making a grander monument to self - love than steven seagal 's on deadly ground .
capsule review : a question : after the floating baby ruth that was waterworld , what in the @$&% were the hollywood execs who gave kevin costner the money to make another post - apocalyptic movie thinking ?
in this 3 hour advertisement for his new hair weave , costner plays a nameless drifter who dons a long dead postal employee 's uniform and gradually turns a nuked - out usa into an idealized hippy - dippy society .
( judging by the costuming at the end of the movie , the main accomplishment of this brave new world is in re - inventing polyester . )
when he 's not pointing the camera directly at himself , director costner does have a nice visual sense , and it is undeniably fascinating to see such an unabashedly jingoistic film in the trust - no - one 90 's ; but by the time the second hour rolled around ,
i was reduced to sitting on my hands to keep from clawing out my own eyes . mark this one " return to sender " .
