It is always said of Stewart that his strength as an actor is his ability to deliver bad dialogue with utter conviction. I say it is time to stop encouraging him. Here's an idea: Instead of giving him bad dialogue, why not give him good dialogue, and see what he can do with that?
[John] Candy, for the few precious scenes in which he legitimately appears (and isn't being dopplegangered by computers or a stunt double), is depressingly good, like a rare form of terminal cancer that gives you the power of flight and makes everything taste like cake. He is able to rise above material that, at its best, is the antithesis of laughter, and somehow manages to be completely watchable and occasionally funny in a movie that is the comedic equivalent of stabbing a weeping hobo to death in an abandoned boxcar.
"And then there's Shaun Toub, who stands out for the opposite reason: He's an honest-to-shit actual actor, and he looks as out of place as a zebra that's wandered into an alpaca farm. You can actually watch the realization dawn over Toub's face that nobody else is doing any acting in this film, but he soldiers on, dedicated to his craft in spite of everything. Toub, who's playing the uncle of Dev Patel's tormented Prince Zuko, is the real tragic hero of this movie, as you watch him struggle to cling to his dignity as everyone around him drowns in narrative sewage."

"And in a twist of fate that I can only call miraculous, Matt Leblanc is not that bad of an actor. I used to think he was godawful in this film. Really, when I first saw it I thought he was the worst thing in the movie. But as I've aged I've began to notice subtle nuances in filmmaking. And looking at it again with fresh eyes some 12 years later, I have come to the conclusion that it's not him — it's the script. Watch this guy and tell me he's not TRYING. He's trying HARD. But the script makes him out to be a total horny asshat who can only spout one-liners. I mean, he hits on his boss's daughter. RIGHT IN FUCKING FRONT OF HIM!!! Who writes a scene that uncomfortably cheesy???"

"Don't try to class this movie up, lady. It's not worth it."
