Why So Ridiculous? Does The Dark Knight Have The Most Ridiculous Film Plot Of 2008?

The Guardian counts down the eight most ridiculous film plots of 2008, and The Dark Knight places at #1 with this entry:

"Wait, so the Joker really orchestrated that big truck chase just so that he could get caught and go to prison, then he could kidnap that guard and grab his phone to make the call to set off the bomb he'd previously sewn inside the henchman in the next cell? That would kill the guy who stole the mobsters' money, thus enabling him to ... er, what? Heath Ledger's Joker may have been a psychopath, but he had a nerdish capacity for forward planning."

And not to mention that Ledger's character tells Harvey Dent that he's a guy without a plan, just "a dog chasing cars". I love the film, but the plot doesn't exactly hold up to the logic of hindsight.
