Is that supposed to be sarcastic? That's exactly what they're doing. Although I enjoyed certain parts of all four Batman movies, they were all pretty awful depictions of Batman. I can't believe people praise Elfman's score for the first two movies either. Are people mixing up the theme from the animated series with Elfman's? They are two completely different themes.
Elfman's stuff is (for the most part) better than what the show had. With TAS every episode had a different theme in addition to recurring villain themes and such. But they all evolved stylistically from Elfman's approach to the matierial. Walker was doing Elfman-lite.
Each show had a different theme? Maybe the instruments changed for different episodes but there was only one Batman theme. I also don't see how it was similar to Elfman's. Just listen to them. I asked one of my friends to whistle "the Batman theme" from the movies and he started whistling the fucking theme from the animated series. He was a big fan of both as a kid and hearing him whistle that theme really pissed me off because if one person can make that mistake and claim to be a huge fan of the Batman movies and the animated series, then there are possibly others making the same huge mistake.
Also, I'm sure most of you know this but when I talk about the theme from the animated series, I'm not talking about the theme from the opening because that one is clearly based off of Elfman's score.
