Well, I read from the issue where Eric the Red first appears and Havok/Polaris go evil up through the end of the Black Tom Cassidy/Juggernaut arc in Uncanny X-men. And yeah, I'm still enjoying it, with the sentinel arc in the middle there especially hitting me better than it did the first time. Random thoughts: They really leave that whole Eric the Red plot dangling for a while. Like, it's brought up as a big "oh man, my brother's trying to kill me, this is terrible!" and it's a whole thing, but then it's shoved on the back burner for like 5 issues, which is kind of odd. Also funny that Jean leaving and coming back happens just kind of because. Guess she was written off for limited ideas, but then they came up with the Phoenix plot and just kind of threw her back in the mix? Also, huh, I didn't really notice the first time around that Wolverine's healing powers were clearly not established at this point. Can't remember when they first actually pop up, but it especially hit me with Jean's "I'm clearly the person for the job of landing this shuttle, as nobody else could survive this deadly radiation" from the lead into the Phoenix stuff. Like, just beam the ability to fly into Wolverine's head and that whole situation probably would've gone less screwy. BTW, was Misty Knight a well established character before this, or did she first show up as Jean's roommate randomly?
Oh, and it seriously is interesting seeing the reprinted letters. In particular, it's kind of funny that they largely seem to rank Wolverine low at first, but that admittedly does seem to be turning around about where I am. But the biggest bit for me may have been how frank the response to Thunderbird's death was. At first it starts with the kind of bs-ish non-answer of "we strive for realism and sometimes people die," but it then went on to be really honest with something like "we honestly saw the least story potential for him due to overlap in powers and traits compared to the rest of the cast" and then brings up something related to how he was similar to Hawkeye, who had apparently been having difficulties proving popular and needed to be reworked several times around then. Just a lot more open than I usually expect to see from such things, which legitimately caught me off guard.
Edit: Mother Panic is more "normal" and isn't anything too crazy yet, but I'm interested in what it set up and REALLY liked the visual design of it, if nothing else.
