I was worried by the 5.6 rating but that's not the reality of this movie.
It's well put together, complex, funny and fun.
Jim Gaffigan is perfect as the two timing dad, he pulls it off with believable self unawareness, clumsily but surely getting himself into and out of tight spots.
All the cast were good and it was a clever and complicated set up to pull off. Writing, editing and directing this piece wouldn't have been easy so full credit for a well executed end product.
The film ending was the least strong part of the story but really where could it have gone and remained believable? It was left a little open ended, and that's probably for the best, although the happy ending junkies that we are would have hoped for a tidy finish, the one they chose left you to think a little after the movie finished.
