Anything after 1986 isn't really the Legion anymore but a confuse pathetic shell of what once was. In my opinion.
I wouldn't go that far - the Legion had some great stories left in it thanks to Levitz staying on the book. Who doesn’t love Quislet, that two foot tin can of pure gossipy ego? It’s funny how the titles that were strong going into Crisis (e.g. NEW TEEN TITANS, LEGION OF SUPER-HEROES) after Crisis felt less interesting and edgy after CRISIS. There was the great “Who is Saturn Girl?” subplot, for instance, which involved a roundabout way to return Princess Projectra.
