Baby Mama (2008, USA)

Baby Mama is an excellent example of material elevated by a good cast. There's little to the script or direction that's original, though I have to chime in with the majority and say that it's quite refreshing to see a buddy movie developed around a pair of ladies. And it's the ladies, along with an amazing number of bit and cameo players, who really make the movie funny. You can tell quite easily when Tina Fey and Amy Poehler are improvising, raising the proceedings above the mundane - the plot still entirely predictable and the ending saccharine, but there are moments of inspiration where the years of comedic partnership shine through.
