I've seen some good blog posts whose tone are generally neutral on Adam-X but who recognize that the character suffers from being underused and never had the chance to evolve (as a character and in design) as did his contemporaries of time the time (gets compared to Shatterstar quite often). I hope they work on a makeover soon/quick -- I'm not crazy with Adam's look in X-Factor #5 (hate the tank top and not crazy about the sleeve tattoos) and worried that gets cemented as his Age of Hickman X-look.
I'd actually love to see a complete overhaul - I think that would really help him shake off the "90s excess" criticisms (the denim and backwards baseball cap are fun, but he'll never move on from the 90s if he keeps them). Even though I thought he looked great in X-Men Legends, he needs to move with the times for the current books.
Just a fun share I pulled off an artist's tumblr (and want to make sure I properly credit the artist: Dima Ivanov):
May be a bit plain but it looks sharp, I really like the minimalist look (and there's something Zen about it this that plays well with Adam's meditative attitude he shows in X-Men Legends), and like how they re-fashioned Adam's hair.
