Not funny enough to be a comedy (although that's kind of a relief for a Sandler movie) and too shallow and cliched to be a drama. It just feels too restrained at times; everything's just so restricted to the banal plot. Drew Barrymore wasn't convincing to me either. She's adorable but not a romantic lead. It's not bad; I just wanted it to go further. I did like the "Grow Old With You" part.
You can not replace good comedy with just a few wigs and crudity. Sandler sure has some potential as an actor but here it is just lazy writing all the way and good old recipes. The 80´s gimmick works about 3 seconds.
