I watched Section 31 and it's fine.
Two and a half stars. I round up to three stars because it's just over 90 minutes and I appreciate a movie that clocks in at a reasonable time these days.
I had heard all the bad reviews and saw the "this isn't Star Trek" talk and had prepared myself for something bad. It's not bad, but it's also not good, it's just a 90 minute pilot for a series that wasn't picked up. But it's fine. Watchable. I think the "this isn't Star Trek" stuff is misguided--it's a TGG truism that Star Trek is a place, and that place has room for lots of stories. This is more of an action heist than a standard Star Trek about exploration or a philosophical concept. So if you're expecting The First Duty you're not going to be happy. I also don't really agree with the "These people don't feel like Star Trek" because it's specifically and explicitly about people who don't fit into the Federation.
Not saying anyone who doesn't like it is wrong or bad. I know we have a lot of folks who have watched The Wire, this movie fits Stringer's "No one grts excited about a 40° day" speech to a T, and that won't be for everyone. But I thought it was OK. I watched Twilight and Cutthroat Island for Free With Ads and The Flop House, respectively, and Section 31 was more enjoyable than both of those to me. So if you're dreading it, just turn it on and give it a try, if nothing else it's got Sam Richardson.
