I am not impressed at all by the end of Secret Invasion.

What a cheap way to [spoiler]bring back a character that's been dead for something like 15 years, and to only bring one back, guess she's someone's favourite.[/spoiler]

But mostly and totally I'm not impressed by [spoiler]the implication that Emma Frost is still evil. She's been on the X-Men's side since 1994 and we just had the "can we trust her" story done and dealt with in Whedon's Astonishing X-Men. The best and only lasting addition to the X-Men team in the last decade is being set up as 'still evil'? Bah to that.[/spoiler]
