If there was one thing that really bugged me about B:TAS, it was their portrayal of Two-Face. I loved the show, but I felt they got just about everything wrong with that character. I didn't like how they made his face blue, or he was created in an explosion. I didn't like that he had an outright split personality even before the incident especially. His relationship with Bruce was probably the thing tha upset me the most. I prefer him being a friend of Gordon and Batman. I liked how after Harvey was scarred in The Long Halloween, we got to see both Batman and Gordon dealing with the loss of a mutual friend. Besides, I dont think Bruce Wayne's public persona is the kind of person Harvey would really be friends with anyways. As we saw in The Long Halloween, he didn't really seem to think much of Bruce and Selina. He thought of them as just your common, rich, high-society type people.
So here's hoping they do a very TLH-like interpretation of Harvey Dent. Heres hoping for that rooftop scene in the sequel!
