2004 would definitely be in my top 3 for that decade. I even enjoyed a lot of the ones you listed that didn’t have critical acclaim. Van Helsing, I, Robot, and Harold and Kumar were a lot of fun at the time.

I didn’t know Collateral came out that Summer. For the most part it seems that August is a dead month for movie releases during Summer, but it is interesting that back then you had Collateral and Signs both coming out in August.
