If it's legitimately a "Jack Ryan with a shield" that it's rumored to be then Fuck Yeah. That's not a cookie cutter superhero sequel. Thats awesome.
For the record, I think the first one was the worst film Marvel did. The quite-literal AMERICA! FUCK YEAH! montage in the middle of the film was bad, the punch-hitler-tour was bad, and they should have set more of it in the present. It had a lot of problems and needed alot of complicated effects (Skinny Steve) to work for a huge chunk of the film. The sequel, at least, can toss all that aside and just make a good action movie without having to worry about a period feel or about having your main character be CGI for 45 minutes.
