I think it looks like it could be pretty good. I didn't get the sense that they were turning Jack Ryan into Jason Bourne or anyone else like that; the fight scene in the beginning looked more like Ryan was a guy just pushing himself to the limit to survive, not a highly-trained killing machine like Bourne.
The rest of the trailer made it look like a pretty standard thriller. It doesn't even look like Ryan takes part in a ton of action scenes (outside of that one bit at the end). I don't think this is going to be a huge issue.
