Alias did the flash-forward thing, too.
I'm kind of intrigued by it--I don't think it hurts the show in any way, really. Not that much was changed--Lynette's kids are truants (is anyone really surprised?

), Bree and Orson are back together, Kathryn is part of the group. The only big shockers were that Gabby has adopted (?) kids and Susan is married to someone other than Mike.
Personally, I like that the season wrapped up neatly, and that Kathryn shot her evil ex (and that it was deemed self-defense!

). I liked the revelation about her daughter, too--did not predict that one!
One question--how did the real Dylan die?

I mean, how would a little kid manage to flip her bed over on herself?
