It's not like this needs to be a big, ongoing line anyway but I'll take Quorra and Sam, a Kevin in white, Clu, Tron and Kevin's old school lightcycle in a heartbeat. Hell, I'd even go for a Castor and Gem too if they bother before calling it a day.
I agree, without the two tone black/gray and white/light gray, and without the lights the costumes had, they're fairly drab. Probably the best we could get for figures, though.
Quorra looks good except her hair looks too textured. It's a sleek bob of straight hair with some flippies on either side - it shouldn't have so much texture between strands, it should be smooth like the Stepford Cuckoos.
