The problems I have with this movie
1) The story: "we're each other's opposite, we're both crazy but i'm different ways, I made this guy but this guy made me, we'll joke around together in the second act and in the third there will be a big fight, and oh there's this screaming lady one of us have to kidnap and another to save" and it is overall lazily wrote
Seriously, it's nothing new, it's bland and predictable.
The Joker killing Bruce's parents: This felt wrong, it completely alters the great equilibrium that was in the comics, it just gets awkward and kind of lame.
2) The supporting cast: Eh, the only guy I really liked was Alfred, the other characters were disposable and really forgettable, Jack Palance and Billy Dee Williams (which was introduced in a pretty bad way, like oh yeah this guy's the district attorney, keep him in mind, we may need it later) were the only good actors. Commissioner Gordon is horrendous and it really murders a great characters.
3) This movie is not dark. It hasn't got the psychologic deepness of the comics, if not some bits in the titular character, it's not daring, it's just can't be compared with The Killing Joke or The Dark Knight Returns, which it is said to be based but it's actually not.
4) Out of characater: They gave too much information about him and his origin story is pretty dope. Here the Joker is just a crazy b****rd, in TKJ and TDKR, which again this movie is supposed to be based on, he is a crazy b****rd too, but he's an AWESOME and sometimes even complex crazy b****rd, here not much, he's just a slightly above average maniac gangster. I don't particularly dislike this version, mainly because Jack Nicholson, which is the most awesome psycho ever, but it just didn't felt appropriate.
And the famous "WANNA GET NUTSSSS?" scene, which is downright ridiculous. I'm not the first one to say this, but the character of Bruce Wayne is just too weird, if someone told me "Hey that guy was actually Batman" I'd be like "Eh, I thought so"
The fact that batman kills didn't disturb me very much, but here it was done pretty randomly, it just distracted me.
5)The batman costume *beep* sucks: Fact.
What's good about it?
Nicholson's lovely campy portrayal of the Joker, Keaton's menacing and gritty version of Batman, which is probably one of the best Batmans ever, the directing, the effects, the score and the overall atmosphere, very noir and stylish, a lot like the 30s and o bit of influence from 70-80s comics (which is probably the best batman period)
It's not bad, but it's deeply flawed and nothing more than an average blockbuster.
And, no, I'm not a nolanite, the only movie more overrated than this that cames in my mind is The Dark Knight, Batman Returns is much better.
This signature is hilarious and original.
NAAAT!
