These movies are like the Transporter franchise, the plot gets more ridiculous as the series goes on. They've been fun, though.
Does it bug anybody else that Han keeps getting included in the movies that don't take place in Tokyo?
They have. The producers recognize the level of cheesedick they're putting to film and just run with it. It's part of the appeal.
Really? I can get liking Fast Five better, but 2 was trying way too hard to be cheesy, and 4 took itself too seriously but was mostly just unmemorable.
