I'm not sure. Sometimes I think movies can be situational, kind of like songs, in that it can depend on your mood how much you enjoy them. I also think expectations or preconceived notions can factor in. He is so unique that it may have just been a matter of getting used to his style.
I think for me expectations or preconceived notions can be the make or break of a film, especially the more offbeat ones. I do really want to see more Wes Anderson films, just for that reason.
I might have already posted this, but I looked up the Wes Anderson films that were in previous Hofs, and they did surprisingly well, usually finishing in the middle of the pack or better.
