W. shouldn't have come anywhere close to getting 4 stars. For Ebert that seemed like a classic 2.5 - 3 star movie. As for the changeling, I don't think it deserved 3.5 either. Its wierd because the filming was great and the acting was good, but the story itself is what I had a problem with. The plot was so crazy that the simple "based on a true story" disclaimer could not make up for the lack of plausability.
