I liked the line-up of Mighty Avengers, but it felt a lot more 'Defenders' than 'Avengers'. It also had terrible timing, as the Axis event just made the book feel awkward.

Blue Marvel > Sentry, though.

And I wouldn't bat an eyelash at an all-male Avengers, so all-female Avengers is gonna have to come with good stories, just like any other book. I'm hoping they don't treat it as a gimmick.
