the live-action movies are as follows: Batman, Batman Returns, Batman Forever, Batman and Robin, Batman Begins, The Dark Knight, and The Dark Knight Rises
I wouldn't say soo... Batman and Batman Returns are different. I suggest watching Batman Forever before Batman And Robin though, as that follows on the plot more.

horror movies
As long as the child understands that it is only a movie, and not real. Then no, I do not think they are a bad influence to kids. I grew up watching horror movies, and now they are one of my passions. I am a horror artist.
