How could they do it! I've not seen the new American version of the film but I bet they've completely ruined it. If you've not seen the (subtitled, ignore the dubbed vers) French original go rent it, especially if you like cars and zany (maybe slightly geekish but accessibly so) comedy. Mind out for general spoilers below so don't read on if you want to watch it from fresh.
The French original has to have absolutely the best ending in any movie ever. Well, if you like cars and the bad guys getting what's coming to them. It just hits you without warning after this great, quite mad, chase sequence and the surprise and the situation they're left in before the credits roll is very cool. I bet the only thing the remake has going for it is the hot model-chicks.
