Generally, most people like comics to remain comics.
Batman is really an exception, stronger and deeper characters made it enjoyable as a movie too, also because actors themselves are able to show better their talent with batman characters. Not even Batman is perfect, though, the first TV series was so trash to become unintentionally comical. Anyway, not even Batman is perfect, though: TV Batman was trash for many other reasons too, but Batman is at risk whenever Robin appears, he's quintessentially trash.
