Iron Man was the first MCU film.
And Andrew Garfield was a poor Peter Parker but a good Spiderman. Just as Toby McGuire was a good Peter Parker and an ok Spiderman. Hopefully Tom Holland is a good in both roles. He did well in his small role in Civil War.
I couldn't agree more on McGuire, which is one of the reasons I really never liked the original Spiderman trilogy. The first two were ok, despite my disdain of McGuire as Spiderman, but the 3rd was so bad that it completely ruined that franchise for me (X3 almost did the same for the X-Men franchise). There were also some minor details that were different from the comics/cartoon that soured me as well, such as natural webbing vs. cartridges, the Venom storyline, etc.
I also agree on Garfield. A very good Spiderman, but a poor Peter Parker. I thought the first Amazing Spiderman had a good storyline with solid acting throughout. An enjoyable film that flowed well, even if it was a bit underwhelming for a superhero movie (I feel the same about the Hulk with Norton). The 2nd movie was simply terribly written, and even some solid acting couldn't save it. Not as bad as Spiderman 3, but the last scene with the Rhino basically encapsulates just how poorly written the entire film was.
As a side, I really bore of superhero films killing off major villains at the end films. Especially when the acting is great. It's nice when they leave open the possibility of bringing that character back.
