Honestly, The Hangover isn't really the sort of movie that I'd break down the doors at the theater to see. Sure, it looks funny, but it doesn't look so funny that I'd feel inclined to pay $10 to see it in theaters instead of $5 to watch it at home. Why then is it on my to-do list for next week? It's because I suspect that every "bro" from here to L.A. is going to be quoting every line of that movie so often that I won't actually have to see it to know what happens.
Like I said, I do want to see it eventually. The problem is that hearing it in drunken quotation form pretty much kills the humor, because you already know the jokes before they're coming. This already happened with me and Old School. I missed it in theaters because I was studying abroad when it came out, and when it came out on video nobody insisted that it be on the top of my must-see movie list (apparently because they all presumed I'd seen it already). I'd caught bits and pieces over the years, but by the time I finally sat down to watch it in its entirety, pretty much every thing that would have been funny because it caught me off guard had already been ruined.
The band's rendition of "Total Eclipse of the Heart"? I'd already heard so many people do that one at karaoke I'd almost forgotten that it's not supposed to have "fuck" every other word. The streaking? Blue dying? Heard it all months in advance.
So this time around, I'm getting in on the ground floor and seeing Hangover before everybody else decides to quote lines from it to cover up a lack of original wit. Now here's just hoping all the best lines weren't in the trailer.
