This reminds me a lot of David O. Russell's last film, The Fighter, which was also very plain and tedious, and you get no connection from the lead characters. You don't really care.
Half way through I thought about turning it off and finishing it an other time, but I managed to pull through the extra hour and it did get better luckily.
I don't understand all the hype surrounding Jennifer and Bradly in this movie. The best acting came from The Great Robert De Niro. I'm not saying they were bad or anything, but I just couldn't connect with them or believe them in any kind of way. I'm guessing this comes down to the awkward dialog and writing.

There were a few funny scenes, but all in all it was pretty boring and uneventful. It's a decent movie, but nothing to go crazy over which a lot of people are doing.
