Input: Consider Input: Review: Besides all of the technical mistakes ....How about a female flight attendant who's able to kill, all by herself, 4 out of the 7 terrorists (including ex marines), 2 of whom without even using a gun. Then, she lands the plane perfectly. We're not talking about Sigourney Weaver or Linda Hamilton; we're talking about a regular, frightened, yet very well composed flight attendant. :D How about the leader in charge of the assault/rescue squad, having a full-proof (according to the logic of the script) plan of sleep-gassing everyone and having someone from his team fly the plane. Only he decides at the spur of the moment to change plans and instead lead an attack on the terrorists, guns blazing, not knowing where the terrorists are, or how many, and not securing a position of advantage, so that his whole team gets easily wiped out. Yeah, that's using the old noggin. Only later to decide to use the sleep gas anyway. And it turns out useless for all intensive purposes.Bad as this movie was, though, I couldn't stop myself from watching and wondering, what next? :D I can't help but imagine all the excellent, unemployed script writers thinking to themselves, it's not fair. lol! :D Question: is it a negative review?

Output: yes


Input: Consider Input: Review: I recommend families if possible,to show this to older children only.Some of the stuff in this film maybe too disturbing for little ones to handle.Now that thats out of the way,let me explain about this movie.This is in reality a documentary of a male fox,who in the beginning is protecting his territory and seeking a mate.The beginning with the gorgeous sunrise and music score,is breath taking.You had better soak in as much of the scenery as possible,it'll get ugly later.They gave both the fox and the vixen names,but I can't remember what they are for the likes of me.He fights off this invading male,to win her love.They later on create a den,and the vixen gives birth to four adorable cubs;one of which is blind.There are many happy and playful moments featuring the fox family,but tragedy and bad luck strike all too soon.The first victim is the blind pup,who gets too close to a high tide and is washed away.The second victim is the mother,who while stealing chickens is deceived by a dead chicken hanging on a pole.She unknowingly walks into a foot trap.While trying to escape she rips off part of her foot,causing her to bleed to death.The rest of the fox family is forced to watch her die under a tree.The male is now a single dad,forced to take on the roll of mom and dad.He alone has to teach them the skills they need for life.It later proves not to be enough,when two of the now grown pups meet an ugly fate of their own; thanks to the carelessness and cruelity of man.I won't spoil the surprising ending for you,but it does show the farmer and his dogs close on his tail.And it is a well deserved ending after what the audience and the fox family was put through.I wanted to say that I saw this when it first came out in early 1980s, when we had a thing called Showbiz cable.I was only 4 when I saw it,but I could never understand why they wouldn't let me see all of it.Now I know why,after I secretly watched it when it came on Disney,when I was 9.I felt emotionally gutted after seeing all this evil going on.I was moved to tears.But as dark and ugly as it was,it serves a purpose.To let people what is going to these and other kinds of animals,and why they are endangered.This documentary wanted to get the message across about this endangered species,and I hoped it worked.Its not fake like the True life nature films by Disney,they don't teach about why animals are going extinct.The encroachment of land,the killing off of the foxes main prey,and senseless killing of these beautiful animals;has resulted in them becoming endangered.I wish they would make sequel to this movie,(Glacier Fox 2005)to see if they're being treated better.Maybe have it be about a vixen pup named Teresa and her siblings growing up.This movie also kind of reflects what happens to human families sometimes,especially when one of the parents suddenly dies.The surviving parent takes on the roll of both,and tries to teach the important lessons of life.It isn't always enough to protect them when they're adults,especially when some of their lives becomes ruined.Or they fall victims to tragedy themselves.Best all around soundtrack and musical score I've ever heard.
