This review (a few spoilers, but nothing I would not have guessed) is from Variety. In my opinion they write the most reliable reviews available. Most of all, they do not conflate or blur together predictions of quality and predictions of commercial success. Variety, which is written for industry insiders, evaluates movies explicitly in both terms, and also for overseas box office. A newspaper also will hire a movie critic to meet the tastes of its readers, but this is typically at a lower level.
I do believe it will be awesome.
Thanks to Todd Zywicki for the pointer.
Addendum: Here are more reviews, no spoilers.
