Well... I grew up on X-Men. But I haven't liked what they did with them since before M-Day. The Fantastic Four did a couple neat things when Johny was trapped in the other dimension. And I did like a lot of the Ultimate Spider-man stories. Aunt May was so cool there. And X-Force was awesome when Yost was working on them. But I really don't like the things that have been done lately or any of the future plans.
DC i liked when the characters had real morals and different values. Now everyone feels like 'I want to be as angsty as Batman'. The Blackest Nights event was awesome. But they did so horribly with it afterwards. I did like the Aquaman reboot for a while. Several of the things they did with the Red Lanterns were nice to see.
And I really happy about the return of Angela in comics in general. It has been interesting to see Scottie Young's work on different titles like X-Men and Oz. Soulfire and Fathom still catch my eyes sometime. I haven't flipped through Witchblade in years.
But none of them lately have given me the developing story that doesn't feel like it will be flushed in one issue lately. So I guess I was a comic fan but not so much any more.
