Posting a few thoughts as a comment to keep things somewhat unassuming.
I was at least expecting a fun action movie but the choreography seemed weird and stilted, like they pieced it together from rehearsal footage. Also it was painfully obvious that the script everyone was reading at the start of the movie was dramatically different from the one they were reading at the end. Otherwise it was bland, inoffensive and uninteresting.
It was a rompy oceans 11 in space. Felt totally disconnected from star trek.
The nano being that could take over any computer system is a little overpowered for the story. So the stakes were not compelling.
It felt more like a Netflix knockoff Fast & Furious plot.
Section 31 in general should just not exist in Trek, let alone get a dedicated series or movie. It is the lest Trek thing in all of Trek canon.
