Bendis is another Ellis-esque "lets totally change Kitty's personality and who she is dating so that she can date my self insert".
Also the O5 could have been good as a temporary thing, but much like with most of what Bending does, he overstayed his welcome and it ended up being a pointless inclusion with no clear end or real growth for either the original or the current version.
He's probably tolerable for minis and clearly defined ending shorts, but as the author of an endless ongoing narrative he's awful. Which isn't unique to him among marvel writers lately but is still true.
