I decently enjoyed it and it definitely turned out better than I was expecting. Fun to watch and a good addition to the MCU.
Pros:
Acting was all really solid. Rudd was a good lead.Lily nailed some emotional scenes. Pena was purely comedic but did it well. Plus I actually thought the villain was well done and his motivations understandable, but would liked to have seen more.
I enjoyed that they embraced and had fun with the setting. Seeing a fight take place on a Thomas the Tank Engine set was fun.
The consequences of fights seemed to come across as a bit heavier. You seemed to believe more that the damage of a bullet will be pretty devastating if it hit Rudd.
Comedy was fun, and made the cinema laugh more than once.
Cemented itself nicely within the MCU
Cons:
The score was uninspired and unimpressive. Really generic boring stuff and a real letdown. The only enjoyable part was the iPhone music scene, but that lasted all of 10 seconds.
The film didn't seem to know what tone it wanted and would chop and change at weird times, and I feel like it would have been better served with more of the comedy being visual that relying on little quips from Rudd and the role of Pena.
The pacing felt a little too fast, and it seemed as though a lot happened that we weren't invited to see. I think peoples complaints of Cross would be solved through devoting a little more time to truly fleshing him out. But what was there for him seemed alright for me.
The camera work was rarely impressive and a lot of the film relied on purely CGI, which is fine for itself and I think it was well, yet it was all in all fairly bland visually. Although I will say I enjoyed the way the fight scenes were filmed in dealing with both sizes.
Overall a really solid film that was consistently enjoyable to watch.
