I thought it was neat that he built an anti-grav system for Martha Johanssen, so that she could fly around and not be stuck immobile, like a goldfish in a bowl. That and being more or less homeless, rejected by his adoptive parents, and addicted to a power-enhancing drug because he was a marginal telepath without it and wanted to feel powerful and important and popular. He had a lot of potential to go either way, into full-blown villain, or to build on his kindness to Martha and ability to gather together other marginal or neglected mutants, and become a new young mutant leader.
But he's changed so much, in powers, background and personality. He's an entirely different character, and one that's not nearly as potentially sympathetic. If Morrison's Quire came back and replaced the one that's replaced him, I'd be willing to give OG Quire a chance, but the current character is not someone I want to read about. (And, frankly, there's at least two dozen people ahead of OG Quire on the list of young mutants I'd want to read about!)
Everything *this* Quire does (attitude, telekinesis, former rich kid thrown out by the fam) Hellion does better.
