Galaxy Quest underrated while Avatar completely overrated
Anytime people bring up Avatar, they're always talking about how great the visuals were. Personally, I found them unconvincing. But worse, they never say there were great performances or a great script, because obviously there weren't any.
GQ deserved so much more. If you offered me $100 to watch Avatar or let me watch GQ for nothing, I would choose GQ. The visuals were okay although not perfect, but the cast was outstanding, especially Rockwell, Rickman, Colantani, Shalhoub and Long, and the script is wickedly funny. I just think it's a much better movie and Avatar seriously doesn't deserve to be the #1 box office draw of all time.
