It was pretty good, but I don't think it held up well compared to the first two. They set the bar pretty high, and this one didn't quite clear it. Plenty of funny, but the whole thing with Artie felt a little empty since we don't know a lot about him, and thus don't have much reason to care about him, no matter how important we're told he is. The subplot with Prince Charming was weird. He's a struggling dinner theater wannabee, because he never got his Happily Ever After? He seems really committed to the craft, though, which is admirable. Too bad he completely and totally sucks at it.
It also felt like they tried to cram a lot into it, to give the audiences "more", but it didn't always work, given the relatively straightforward storyline.
Not bad, but still the weakest of the three.
