Still the best superhero origin movie for me. Good blend of humor, action, emotion, great character arcs, intriguing origin story. RDJ gave one of his best performances in the role of Tony Stark/Iron Man; and I'm happy that this role also helped renew, boosting his status in Hollywood.
The movie was also a dream come true for an Iron Man fan like me, to be able to see my favorite character get brought onscreen and done justice, it's just great.
Nothing in other superhero movies has come yet to replace the cave scenes as my favorite scenes ever; Avengers assembling scenes/tracking shots came kinda close though, but mainly cause I'm also an Avengers fan, so it's all sentimental.
I especially love the character of Yinsen, the kind man who helped shape and influenced the change in Tony Stark into the hero he is now.
Iron Monger might not be a great villain, not even close; but Obadiah Stane is, at least for me. The slimy, backstabbing, despicable, power-hungry industrialist bastard put great physical damages on Tony Stark. But what more cruel is that he's who Tony thought of as ally, friend, mentor; thus, the psychological and emotional damage he inflicted that sure to stay are much more of why I think he's the best Iron Man villain yet.
I adore Pepper Potts in this movie, not much in IM2, and she was okay for me in IM3. I love her for who she is, an independent, stern, charismatic, and kind woman. I also love her relationship with Tony Stark this early: flirty, teasing, snarky boss-secretary; I like how she understands him, how she can put up with his shit, but also can tell him off.
Overall, yes, it's definitely one on the Top 10 of my most favorite superhero movies, and the best origin story. It's an A
