I keep reading reviews for Cars 2 and I am kind of surprised. Some people went as far as comparing it to the Star Wars prequels. Sure, Cars 2 definitely is no "Finding Nemo" or "Toy Story." But it sure was fun, at least for me. The plot was an obvious reference to James Bond and Mission Impossible. I enjoyed the spy gadgets and political overtones. It was action-packed and not only enjoyable for little kids, but for older kids and adults too. Why all the hate? Heck, even Roger Ebert and Rolling Stone liked it!
In my opinion, Cars 1 was a little slow. It dragged a little too long in certain parts. Cars 2 suffers from no such thing.
To sum it up; Cars 2 may not be Toy Story but it sure is FUN and ENTERTAINING.
