You know, I haven't read the entirety of the thread and only skimmed the article, but a couple of things I have to say about repeat viewings of films:
1. I really dig seeing flicks in the theater. Probably cause I don't have a 20 foot tall screen to watch movies on at my house, or a comparable sound system. So if a movie that I like a lot is enhanced by the theater experience (especially sound design, you can really appreciate good sound design if you sit in the acoustic sweet spot in the theater), I'm probably gonna see it multiple times.
2. Up until about a year ago, I had a lot of friends and acquaintances. Quite a few of them worked in the film industry, or were trying to. Of course they're gonna wanna see lots of flicks. Not everyone can go see a movie at the same time. Sometimes, if I enjoyed a movie I'd go see it with multiple groups of friends. Of course, people who write for a film blog might not have so many friends.
So yeah, anyway, I don't think it's really very embarrassing. Now, fanthings that dress up as jedis to go see Star Wars flicks and shit like that, THAT'S embarrassing. Me seeing Children of Men multiple times in the theater = not very embarrassing. Or at all, really. I did see TDK twice, a Friday morning screening by myself and a Sunday afternoon screening with a friend. Lots of other people have done so as well, and others have said their opinion of the film improved after multiple viewings. So, anyway, dude is a wanker.
