The Dark Knight Returns
Here's the deal--I like this story, but I don't love it. It's grossly overrated. It's a good story, but as a Batman story, it's not very good. I'm not sure why people continue to praise the crap out of this comic. I appreciate what it did for Batman and comics in general, but that still doesn't mean I like it as much as everyone else.
Batman: The Long Halloween
I liked this when I first read it, but after I thought about it for a while, I realized that the twist ending was complete bull crap. Where were the hints? You can't just throw your audience a curveball without dropping clues. The ending just makes no sense. Also, the middle of this story drags really badly.
This book has all the same problems as The Long Halloween.
Batman & Robin
Eh... I just don't like it...
This story is crap. There are some interesting ideas present, but none of them are executed very well, even though this story is 14 ISSUES LONG! This story should've only been six issues. This story made me hate Carnage. Want a good Carnage story? Go read The Amazing Spider-Man #361-363. That's some good stuff.
