Example Input: deep focus . I've taught this film in colleges for thirty-plus years. Even back at the earliest screenings, traditional-aged freshmen had trouble with it (a) because it was in b&w, and (b) because the dimensional characters didn't telegraph plot advancement but instead used irony, wit, or assumptions that would later be proven wrong by subsequent events. The first of these objections stunned me when they couldn't appreciate Gene Tierney descending the stairs to seduce "Larry" in a gown relegated to grays. The second objection (young auduence confusion) just made me sad about the impact of television ... but you already know that story. As with Hollywood's THE PICTURE OF DORIAN GRAY, released in during the same general period, I personally appreciate the "epic scope" of the narrative, enhanced by remarkable set direction detail. And I appreciate even more the depth-of-focus photography in both of these films, which enriches viewing by sharp images at several planes of action within the frame. It's a story well-told at the visual level. I've read complaints about Tyrone Power's "dated" acting in this performance, NIGHTMARE ALLEY, etc. But again, I suspect this is from a generation more comfortable with MTV editing than with theatre as an entertainment criterion. Power is given a series of difficult monologues to recite about uncinematic spiritual/ philosophical themes, and he pulls each off brilliantly. As with Olivier's opening scene in RICHARD III, it's interesting to watch how these monologues have been directed to use a pacing movement of the actor within the frame as a "paragraphing" punctuation. The lengthy, uninterrupted takes and consequent fluidity of camera movement within these shots not only enhances the impact of the monologues but also makes sly commentary on characters/ themes as continuous camera includes other characters in medium close-ups. Herbert Marshall's Maugham is interesting and underplayed almost as masterfully as Cedrick Hardwicke's performance of "goodness personified" in ROPE. The close-ups of "Maugham's" eyes to communicate ironic plot points may seem obtrusive, but they're true to Maugham's voice in the novel. Further, they emphasize the ill-advised decision to omit this narrator's perspective in Murray's hapless remake. That later film fails in no small part because the female characters are virtually indistinguishable visually, and because the studio (which only made the film to entice Murray to make GHOSTBUSTERS II) invested no interest in producing a good movie script. Pity, since Murray could have done okay. Two less successful scenes in the 40s version are the "Baby!" hospital melodrama and the ashram Jehovah sequences (not including the remarkably visual spiritual moment in the mountains). But the supporting cast remains superb throughout--especially the bracing comedy of Webb and Lancaster, and the moving subtlety of John Payne and Lucille Watson. Tierney's richest moments are linked to the plot: "That's all right, Larry. It might be less than a year"; the wedding announcement over the phone; the camera-narrated scene where Isabel "seduces" Larry's fiancee; and, of course, the climax with Larry at the end. And, by the way, she's as gorgeous as Tyrone Power! How much more value can one expect from an entertainment that succeeds so well with complex, mature themes of spiritual redemption in a society of capitalist myopia?

Example Input: hated it !!! . i have been waiting to see this film for a while now. and i just finally saw it i'm very dissapointed. this was nothing but a low budget horror flick with cheap trills. the film sucks!!! the nazi zombies coming back from there watery graves to terrorize modern day tourist that are in a small boat. and get stranded on a deserted isolated island. was a great! idea except that with this film you're going to be very bored and dissapointed if you ask me. i was expecting a lot more than this the zombie nazi's make up looks silly. they're not even frightning or scary they just made me laugh. the picture quality has aged even if it's dvd format very grainy poor picture quality. i have seen other movies from the 1970's on dvd and the picture quality looks excellent almost like new or like it has been digitally remasterd for it's age. but this was awful. the only good thing it has was decent acting lol. like i said before this is nothing but a (low budget cheap horror film) rent it if you like. but dont purchased it it will be a waste of your money and time.

Example Input: Roaring biplane blast from the past! . My father took me to see this movie when I was a child of about six or seven. Actually, he wanted to see it and he had to take me along. I didn't remember the plot, but I remembered the scenery and the music and the cool biplanes and dogfights. So, I finally bought this movie so I could watch it as an adult. I can empathize with those who say this movie is too long and moves too slowly. That said, I enjoyed it more than I thought I would. The airplanes are amazing. Where did they get all these biplanes from? The only other movie I've seen that has such authentic looking biplane dogfights is "Wings", and that was made back in the 1920's when biplanes were all over the place. The soundtrack by Jerry Goldmith fits the movie perfectly and adds mood where appropriate. I loved the "intermission". It reminded me of a time when a movie was a real event. Movies were so long that the movie itself gave you a break to use the bathroom. I saw this movie in a theater that was designed to allow perhaps a thousand people to watch a single movie on a huge screen, not some modern "plex" theater that has twelve little rooms where you can pay to see a movie with a bunch of strangers a few months before it's out on DVD. So, it moves a little slowly by today's standards, but it's epic, and it's interesting to watch Peppard's character slowly alienate himself from his squadron, and his lover, so that at the end they kill him off by giving him the "privelege" of flying an experimental aircraft.
