The Toymaker works in his introduction for a brand new generation - threatening, intimidating, and his immense presence assured from the start, and Neil Patrick Harris delivers a strong performance.

His scheme, doesn't hold up to much scrutiny, but as his villain presence is good, I'll let it slide.

My nit-picks are common criticisms from others, so I'm not offering ne insights. The Bigeneration, and the reason for the face returning feel forced and unexplained - it doesn't feel earned. It certainly doesn't ruin the episode by any means, and it isn't canon breaking for me, it's just not narratively satisfying.
