I was sort of thinking the same thing.
I understand what he's saying about Iron Man possibly having the advantage due to people being freshly geeked about it, but rating it up against a sequel is ridiculous.
I invite anyone who has the time to rewatch BB now that IM is fresh in their mind and vote here, on the grounds that they are both origin superhero movies.
Not on the tone of either movie, whether it be dark or lighthearted shouldn't cloud someones decision as to whether or not one movie is overall better then the other.
Instead consider casting, directing, scripting, visuals, and whatever you think might factor in to make one edge out the other.
The reason that rating it up against TDK is unfair is because sequels to these movies have tended to almost always be better then their opener, they learnt from the mistakes of the first one, they've gotten the origin out of the way and already started developing important characters, basically everything is set in place for a win if you had a good concept to begin with.
What amazes me with Iron Man is that it got past that initial first movie flawlessly in my eyes, and for once I didn't leave the theater saying "this was good, but they've got things to fix for the sequel."
Watched it in the last 2 weeks & I still think Iron Man is better, I personally never based it on the mood of the film or realism BS. I just have so many nit picks with Batman Begins. Acting wise I didn't like Christian Bale as Batman that much don't get me wrong he's a great actor but it didn't quite feel right for me. Katie Holmes, do I really need to explain & the fact they created up a character called Rachael Dawes when they could of picked so one of the many interesting girls from the Batman Comics. Cillian Murphy was a wasted opportunity, great actor, great performance, shame they gave him little on screen time & a poor story. Liam Neeson was much the shame, & Ra Al Ghoul should of never been killed. Gary Oldman was the only thing I truly loved about the film but failed to get enough screetime, he really is the perfect Gordon. Michael Caine as Alfred was an usual choice but he pulled off a great performance & some much needed comic relief. The finale was poorly executed & very dull for a Comic book movie especially around the time that water-air-molecular thingy machine came into the equation. I disliked the tumbler from the moment I saw it, again they could of taken some inspiration from the comics. The script was weak at times in so many places, the dialogue was sometimes out of place, but at times had some truly original idea's (probably Nolan's bits).
I went into Iron Man thinking its going to be a fun comic book film which will probably suffice my needs. But what I got was that with a semi serious undertone, possibly one of the best casts in any comic book film including Robert Downey Jr., one of my favourite actors. The film stuck pretty damn true to the comics minus switching the captor's. Robert Downey Jr. is possibly the best fit for a character from a comic book yet, Paltrow was great as Peeper Pots, Jeff Bridges put in a solid performance as Obadiah Stane, & Terrence Howard was as likeable as ever. The Mark III suit, was simply perfect as was the other Mark suits. Iron Man had a fantastic first half, while the second half was almost as good but lacked ever so slightly in the finale. I admire the fact that they choose to have Pepper & Stark never actually getting it on, since like so many films they could of just stuck a little kiss in there at the end but I was pleasantly surprised they didn't. Throughout the film you really did see Stark's character go through a change of character. Iron Man's script knew what it wanted & didn't stumble once, great tale of Iron Man's origin's, the film went along at a good pace never getting stuck in one particular part of the story, & the dialogue was snappy & fast.
Batman Begins is a good comic book film & a worthy Batman film but just has a few too many flaw's in my opinion (An opinion cannot be wrong).
Iron Man was a perfect start to a franchise, never really let down in any area (acting, story, effects, music, etc) providing a very satisfactory film, were I never went I wish they had included or done that.
But when it comes down to it both are great movies, I just so happen to think Iron Man is the better film, sue me.
