While I was a huge fan of the writing, pacing, acting, and overall production of the first two Captain America movies, I found this one to be pretty boring. It wasn't paced very well. I wasn't all that invested in the narrative. And the major fights were just so-so.
I also hated the new rendition of Spider-Man, and have grown pretty tired of the depictions of him as a high-school super hero despite him having so much more complexity in the comics.
