Pleasant Family Film with Laugh-Out Loud Moments
14 January 2011 | by (United States) – See all my reviews

I confess that I don't understand the negative ratings for this film. Maybe you need to watch this film with your kids to appreciate it. Overall I found this a very enjoyable family film, with good work by some fine comic actors. Doris Neely is very funny. Andy Richter and Tim Meadows also give good comedic performances. And there are some moments of pure physical humor in this film that are genuinely laugh-out-loud funny. Robert Hoffman, as Ricky, gives an amazing physical performance that reminds me of a young Jim Carrey. I am surprised that more attention has not been paid to his movie-stealing performance. There are a handful of moments in this film that had the entire audience laughing uncontrollably. What more can you ask from a comedy? There are the kind of moments where your kids will ask you to rewind and watch it again. Why? You ain't seen nothing until you've seen Funky Ricky.
