Mysterio is a joke.
This has been known to anyone with half a brain from the get-go. The good thing is, the early reviews from actual critics (IGN has theirs up, Levy has his, Variety, Hollywood Reporter, etc.) and not AICN people seems to be pretty much entirely good, save for Variety. It's at 86% at Rotten Tomatoes, and I bet it ends up with 79 to 82% fresh. The reviews seem to say the same thing, this is surprisingly good considering the amount of subplots included, the action set pieces are top notch, the film serves as a fitting conclusion to the series (or at the very least, the Osborn arc) and that it rests between the original and Spidey 2. But it's no Spidey 2.
