Two words that come to mind are illogical an absurd. What guy is going to go on a vacation to Hawaii with his supposed wife he is divorcing and kids and bring along the new woman he is leaving them for? They all pal around Hawaii together like they are a big happy family. What girl would be excited about marrying a guy who is constantly ripping on his wife in front of her? Sandler spends more money than the Prince of Dubai during this movie in an effort to cover his tracks. His sidekick friend in this movie was pathetic and not funny at all, but at least I didn't have to see the usual Rob Schneider cameo.
There were a couple scenes that made me laugh, but overall I felt this movie was totally fake and very predictable. So I give it 6.2 stars. If you want to see a better Sandler movie, watch the Wedding Singer or Happy Gilmore.
