As the thread description states, spoilers ahead, so if you haven't read either (and you really should) stop reading now. I'm just going to keep typing like this so it looks like a whole paragraph, and then the next paragraph is going to be spoileriffic. But a paragraph is more than 2 or 3 lines, so I'd better type just a little bit more. Anyway, last chance to get off the train to spoilerville is now, just press alt and left at the same time, it's that easy.
So, I noticed a fair amount of parallels between the two (I'm not saying that Crisis is a ripoff of Halloween) but there are certainly striking similarities between the two. Like the fact that the killer is the wife of one of the main players in the story, and that there are several false murderers, or red herrings, I guess.
Identity Crisis is more complex, with Dr. Light and everything (and very cool, especially at the end where Batman is trying to find out what he was made to forget) but the Long Halloween is more plausible, and maybe even a little "darker". Crisis seems to come off as more of a mystery comic, whereas Halloween comes off as more of a dark mystery, if that makes any sense.
Anyway, did anyone else notice this?
