Agreed on both parts. I just youtubed the second ending as I really don't fancy investing many more hours doing all that riddler rubbish.
As for the villains, I too was disappointed. Not only the lack of, but the easy mode that came with them.
Can you clear up the endings for me.
I've gotten as far as beating the dark knight and scarecrow.. I now have the option to activate operation knightfall.. is the the 'real' ending part... I havent done all the riddler stuff or a load of other stuff yet so I'm not sure if there's even more if I complete the other bits as well
