Captain America: Civil War was screened in over a dozen cities last night, and - incredibly - Marvel's embargo on reactions was only a few hours long. Note that this isn't the same as "actual, full-length reviews", but apparently they let people (critics and fans) go wild in posting about specific characters and scenes on their social media platform (kinda surprising we weren't invited to any of the screenings, given the "Marvel Shill" contract we signed a few years ago).
The interesting comparison here is, naturally, with Batman v. Superman, which didn't allow critic reactions to social media until the Tuesday before the movie was released. Meanwhile, Civil War is allowing critical reactions A WHOLE MONTH before the film premieres. And the reactions seem to tell us why - it sounds like they knocked it out of the park, with Tom Holland's Spider-Man and the airport action scene getting the majority of the praise.
In short, Marvel, please honor the terms of our Shill agreement and GIVE US A SCREENING NOW.
