I was like you. I watched "Inglourious Basterds" in August 2009 and then didn't go to the movies for almost a year because every movie I was remotely interested in got reviews that scared me away. Then I saw "Toy Story 3" twice (once with a friend, once with family). The second time I saw it, I saw it in 3D. That was the first movie I ever saw in 3D and I was not impressed. Yeah, sometimes it's cool when it feels like things are coming right at you, but it's not worth the extra money, the inconvenience of having to wear the glasses, and the minor headache it caused.
I'm glad I waited so long to go the movies again. "Toy Story 3" wasn't perfect, but it was worth the ten month wait. I'm hoping I won't have to wait very long to go to the movies again with "Inception" coming out, since that movie looks like a sure thing. After "Clerks II", "Superman Returns", "X-Men: The Last Stand", "Spider-Man 3", and "Beowulf" in 2006 and 2007, I vowed to myself that I would never again go to a movie unless I was really, really interested in it and the buzz was really strong. It sucks not going as often as I used to, but my decision has paid off well. I never want to leave a movie theatre as disappointed as I was by those movies ever again and I think if I keep being as cautious as I've been, the plan will keep working.
