I saw the test screening last year in Pasadena...really impressed by what I saw, but not surprised by the studios stance on reshoots. It was rather bleak, and Max is interpreted as a pretty unstable kid (which would account for the negative reaction towards the performance). It was too dark and complex for mainstream audiences, so this whole clusterfuck getting this movie into theaters is all about the studio retooling Jonze's vision into something more commercial. And for the record, the kid playing Max was AMAZING.
