I think one big problem of batman 2,3,4 was that the fact that they decided to go with 2 villians instead of 1. Batman 3 could have been a much better movie with just Two-Face as the villian. IMHO his back story is glaringly missing from that movie and would have been much more interesting than the back story of Riddler. They had too much to cram into one movie with two villians. I much prefer the the 60's tv series to batman 2,3,4.
