Iron Man 1 totally holds up. The only thing I really didn't like about it at the time was Stark being crippled with the mark 1 arc reactor in the finale. I felt cheated out of a better display of the armor's abilities. But we've seen plenty of the armor do badass shit in the last 8yrs so it doesn't bother me nearly as much any more.
That's also why I'm not as fond of Batman Begins as other people. He gets tooled so many times in that movie, and we don't get a good ninja-Batman like I expected or even unstoppable force Batman like we did in BvS. In fact, he never comes across as particularly scary or formidable in any of the Nolan films so I never felt like I got exactly what I wanted from the character in that franchise. He's always getting clowned in some way in all of Nolan's movies. I don't want an invincible protagonist, nor am I a huge fan of the Bat-god trope, but a little more in that vein would have gone a long way.
