Now, I'm not saying that Open Season was bad, it just didn't "grab me". I found it difficult to work up much caring for what might happen to the main characters in this, though, which was part of the problem. Also, there were glaring holes in the "story logic" ... at least in Madagascar they dealt with the fact that the Lion's buddies were starting to look like food pretty quickly, in this the Grizzly is coaxed to eat one pinecone over a two day period, and there is no hint that all those bunnies, deer, beavers, etc. were potentially on the menu (once they gave up on trying to deal with the ninja fish).
There wasn't even very much in the way of "cultural references" to keep things interesting for the adults ... the "Braveheart" allusions got old fast with the Scottish-voiced squirrels, and there was precious little past that. Even the "human lead" seemed derivative, as she was drawn to look like a grown-up version of the perky redhead girl from Monster House ... why would they draw/voice a character so closely to another one? I also didn't "get anything" from the use of either lead ... Martin Lawrence and Ashton Kutcher brought no more "depth" to the characterizations in this than did Owen Wilson and Bonnie Hunt in Cars (and this didn't have the "playing to type" supporting cast that was backing those two in that)!
Oh, well ... at least we got in at the $5 showing! We also were able to take advantage of the TGI Friday's "Free Lunch" promotion before it ended, which knocked a few bucks off of lunch.
