Would The Dark Knight still be a good movie without Heath Ledger?

ok first off i'm going to point out that i may very well be biased since i am a huge christian bale fan and have most if not all his dvds on my shelves right now. anyway in answer to your question, i think the film would have been just as good without heath ledger in it. whilst he did play the joker pretty much as i imagined him, i feel as though it was the death of heath that made everyone love his role more. whilst i already disliked heath for the way his character treated the jake in broke back mountain (as though it was real life, how sad i am) i felt that the fact that heath is no longer with us made everyone single in only on his character and totally glaze over the other actors in the film. whilst it would have been unfair for the exact opposite to happen, i think people need to remember why the film is called batman the dark knight not joker what a guy or something. as for christian's batman voice, i thought it was a bit silly to start with but considering the technology gotham supposedly has, walking around using his normal voice would have been equally silly no? again i'm biased.
