*SOME SPOILERS AHEAD IF YOU NEVER BEAT THE GAME... IF NOT, THEN WHY ARE YOU EVEN HERE*
Ah well, I just think it's funny that the extended endings are nothing more than what other forum goers here or I have already mentioned. Everything that we were left to come up with on our own was practically what was explained in the DLC. The ONLY real plot hole, which was Joker running away, was even explained. For anyone who hasn't seen or played it yet, I provided a video below. I just find it sad that there are still people crying foul, despite their only gripes being plotholes (that are again explained in the DLC).
