Got my set yesterday. Psylocke is everything I wanted her to be; truly miles above the original one. I really hope that butterfly joints become the new double elbows/knees and all (or at least) most figures start getting them. My only gripe is a small one, which is that I wish she could wear the little crown thingy with both heads, but it seems that only the angry one has the little slots for them. I also don't entirely get how the slashy effects are supposed to go on her hands, if there even is a "right" way. I've found like ten different ways to put them on, and none of them look entirely right, nor do they look entirely wrong. Knowing me, though, the answer is super obvious and I just keep missing it.
Thanos is a perfectly fine figure, but had the misfortunate of being in a set with a figure that everyone was looking forward to above him. He suffers from what a lot of larger figures suffer from with range of movement- the chunky gauntlet and boots don't help either. He's totally serviceable, but there's not much you can do with him, especially next to Psylocke. I'll definitely try and offload him, if anyone is interested.
