Attack of the Cybermen is a perfectly fine Cyberman story that doesn't necessarily do anything showstopping-ly, but doesn’t fail egregiously either. The costumes could have done with more (or... any) budget, but the half-converted human was a fun touch. The side characters were a bit forgettable but I liked the Doctor making mistakes and suffering the consequences of his actions. Peri even gets a normal costume in part 2, which is a sign that the bar is on the floor
