Saw Transporter 3 yesterday. Quite entertaining, actually, well-cast, with a gripping plot, and just the right length.
Written by Luc Besson who happens to have written all the previous Transporter movies, as well as my favourites Fifth element and Leon.
Audi S8 stars in the main role, its exhaust note providing a beautiful soundtrack to some of the best scenes.
If you go watch this movie (and I recommend you do)--leave your critical mind and knowledge of physics at the door so they don't get in the way. Then lean back and enjoy.
