Technically any good? The script was a MESS. Aside from the completely vain choices of the director/writer casting himself as the writer character, this film is rich with horrible dialogue, crappy structure and no logical throughline. Seriously, there are lines of dialogue that don't even line up (as in one line doesn't logically follow the previous one), scenes that don't make sense and some of the most lame acts of contrivance I've seen since the last M. Night Shyamalan movie I saw (and don't even get me started on the racism). The acting is mostly terrible (Giamatti is, of course, GREAT, but that doesn't save the movie) including Bryce Dallas Howard who seems to be caught in that rare place you get in when you're trying to think of a word that just doesn't come to you. She was in that place FOR THE WHOLE MOVIE.
How did it leave me feeling? Baffled. How M. Night can continue to get money is beyond me. He must be a REALLY cool guy in real life because his movies suck so bad. This one is by far his most immature outing yet, feeling like it was made by a 14 year-old kid who thinks every idea out of his head is "so cool!"
Somebody revoke M. Night's Director's Guild card. He really doesn't deserve it and I think that's saying a LOT.
Final Rating? DNS - Do Not See--EVER. It's contrived, predictable, nonsensical trash.
