On the Marvel side, Civil War was actually fairly well-handled, even if the concept was dumb. But Secret Invasion has been a total mess from the start. I still can't make heads or tails of it, and feel like I'm missing half of what's going on. New Avengers' constant flashbacks and side-stories are beyond frustrating.
I can't agree with this. I think it's been superb. The flashbacks are there to explain why things didn't happen the way we thought they did.
Sure, you have to buy a few books to keep up (the main title, New Avengers, Mighty Avengers, The Initiative) but you don't have to read things like the Thor, Spider-Man or X-Men ones.
