Yeah, have heard pretty good things about it so far. I like that Marvel is taking risks with their properties and is not just focusing on the Avengers.
I must have seen pretty much most them (except GoTG and the 2008 Hulk movie I think), but I liked them. Even the Captain America movies, since I never really cared about him but Evans did a good job with him.
Pre New 52 Blue Beetle and Booster Gold back in JL 3000? What gives, does this mean there's going to be a Pre New 52 DC Earth in the Multiverse? Oh I bet that means there is isn't there? Great, appealing to the Pre New 52 diehards is just going to make things worse DC.
The writer have confirmed that JL 3000 takes place in the future of an Earth that is pretty similar to the one before Flashpoint.
You should. Unlike comics like Buffy and Angel the Charmed comics have kept the same sense of realism. They haven't let the fact that they are no longer on a budget let their imagination run wild. Plus they all get new powers which is always cool.
Wish the art was better though. With some exceptions, in the issue I checked, the art was rather weird looking. And especially when it comes to their faces.
