I didn't hate these two episodes.  I liked how we got to play around with the Chameleon Circuit a bit and didn't find Peri or the Doctor that insufferable.  The stuff with the Cybermen weren't great and take up a lot of the episode, but luckily with only two parts it was a short enough experience I could appreciate some of the other fun stuff we were going for with these characters like Lytton and the Cyrons.  The latter look real bad just like the Cybermen, and this era of the show just could not put together decent effects or costumes for the life of them, but it was still at least worth watching to me.
