I can't think of a movie with Kristoffer Polaha that was a dud until now. I loved Holly and Ivy which was the first time I saw Marisol Nichols so I wanted her to do well.
The story is extremely simple and basically a vehicle for a lot of humorous gags. I didn't find enough of them funny so I think this will be a movie that appeals to people who like that style of humor and leave other people like me wanting more. The story is totally predictable. Once you know the setup, it's easy to lay out what the outline for the rest of the movie is going to be. One slight exception is a side romance that totally lacked development and then bingo at the end, it's there. There are a lot of the usual Christmas activities that are so often crammed into these movies.
As for romance there's no chemistry. It was like two actors doing their parts alone or to a blank wall. The plot points were there for restoring the romance, but they made no sense because of the missing connection. It didn't help that Robby had a 180 degree personality change which wasn't really developed. It just happened. And Marisol Nichols, as Becca, lacked any emotional response to those efforts.
There are a couple of scenes which involve alcohol in ways that I think detracts from this being a family movie, but then I also think the subject and humor were probably above the level of children.
