Ok some of the review are in and it was just as I said a ROIT. Haven't seen it yet but here's a clue.

This is a movie that is uniquely, ideally suited for the rowdy, crowded communal experience, the likes of which we haven't seen since "The Rocky Horror Picture Show."

This is an event. It's a rare example of a film not just living up to the hype, but surpassing it. And it's the best time you'll have at the movies all summer, if not all year.

Granted, it's difficult to separate the two — the sensation of watching the film en masse and the film itself — because they're so intrinsically entwined. At a recent late-night showing, for example, a guy wearing a Big Bird mask led the packed auditorium in spirited "Snakes on a Plane" cheers — and this was during the trailers, before the film had even started.
