This is the first movie that I ever recall seeing in a movie theatre, I would have been around 5-6 years old at the time and I have loved it ever since then.
I'm not a huge fan of superhero movies or fantasy movies in general, as I find they're just so far from reality that I just can't take them seriously. I guess that's a part of the reason why I enjoy this movie because it's grounded so much more in reality. Sure, a guy dressed up in a bat costume isn't an everyday occurrence, but he's not doing the usual superhero things like shooting lasers beams, smashing through walls with abnormal strength or anything like that. He's got a few gadgets, a cool lair and just brawls when he gets into fights.
I enjoy both Michael Keaton and Jack Nicholson in this movie. Michael Keaton's performance doesn't possess the suave, cocky personality that many other actors apply to the Bruce Wayne character, and I prefer it this way as it gives his character a more sympathetic touch. While Heath Ledger has since stolen some of Nicholson's votes for best live-action Joker performance, he has a perfect blend of humour and crazy which makes for quite a memorable villain.
This version of Batman has a very dark, murky, gothic tone to it. While there are some comical moments, it's probably the most serious and realistic version of the caped crusader to date and I prefer it that way.
