I found this more than mildly entertaining most of the time. I love Jason Bateman, so I will pretty much watch anything he's in. Same goes for Kevin Spacey. I loved him in this. Jennifer Aniston...well, to be honest, I didn't much care for her in this. I think her character could have been played by anyone (and was it just me? she was looking pretty rough, I thought).
Charlie Day, I also think, could have been anyone cast alongside Jason Bateman and Jason Sudeikis. I do quite enjoy the fact that John Francis Daley was one of the people involved with the screenplay, as I have watched him grow up on screen, and really like him as an actor. This screenplay, not terrible, not the absolute best thing I have seen, but definitely, very entertaining, it stays relatively strong from start to finish. I think it's mostly some casting choices that detract from this for me.
I love that Donald Sutherland, Julie Bowen, and Bob Newhart all make appearances, as well as Jamie Foxx. Great stuff. P.J. Byrne (who??)'s character was a touch too much, I think they carried his initial scene too far by just a hair, but overall, good, solid entertainment.
