HCT is such an incomprehensible story, especially that last issue, a normal person couldn't make heads or tails of what was happening, or why it was happening. You needed some doped out fanboy to explain it online... a theory that was copy-pasted to all the message boards with people pretending they came up with it, acting all smug.
It was like Inland Empire, where you had the devoted Lynch-licker step out and cry "It's brilliant!" not because of the story or the twists and turns... but because it's incomprehensible, and that makes the people who say they got it and then spout pretentious post-modernistic crap about transcendalism and other weird shit with fancy names, just to hide the fact that they didn't get it either.
I didn't find it incomprehensible at all, it was pretty straight forward. Future X-Men vs Sublimed (cokehead) Beast, Jean's reborn, taken advantage of, she elevates fully, cuts off the future by changing the past. Easy.
I mean, there were some more open ended segments and non-linear elements with the Phoenix/time stuff, but even that wasn't too tough. I liked Morrison's more open-to-interpretation framing of things, it made the homage feel extra Claremontian.
