I like them for the most part. I thought that it was a neat story idea to take a group of X-Men and show them what a hell that their lives would become. The problem with them is that their story never really progressed fast enough, and they really didn't do much to have an effect on changing their future. Personally, I find Cyclops to be the most annoying. And Angel's fire wings are pretty ridiculous, and the Black Vortex is about the only story he has gotten since coming to the future
In my opinion, Cullen Bunn in X-Men Blue, and Dennis Hopeless on the Jean Grey solo comic did the most to get any thing out of the concept.
