Checking out early reviews of the Scott Pilgrim movie

The early reviews are largely good at Rotten Tomatoes - though only 3 'top critics' have weighed in so far, two disliking it and one ambivalent - but here's a negative review from the Hollywood Reporter. And it repeats a lot of my complaints about the characters in the book series, which isn't a good sign:

What's disappointing is that this is all so juvenile. Nothing makes any real sense. The "duels" change their rules on a whim, and no one takes the games very seriously [...] Certainly Cera doesn't give a performance that anchors the nonsense. His character sort of drifts, not really attached to any idea or goal other than winning the heart of an apparently heartless woman...

So, yeah. Doesn't sound like Cera or Wright has tried to do much to address the great big black hole that is Scott's character. Or that the latter has tried to limit the magic realism/fantasy in any way that makes it reasonably consistent and not wholly nonsensical.
