I finished up 'Attack of the Cybermen.'
I really like the Sixth Doctor in this one much better. I don't mind his abrasive personality and find him to come off as extremely intelligent.
The story itself is really fun, with the first part feeling like mostly set up, which is how most Doctor Who two parters feel in new Who (it's also interesting that they briefly tried out the 45 minute episode format as it really feels like new Who in that regard). I find Peri to be a bit whiny though, which is interesting because I never found her like that with the Fifth Doctor. Also it's too bad the only other companion Six gets is Mel because I think he would have benefited from a better character to play off of.
Personally, I hate "Attack of the Cybermen." It's too gruesome, especially when the Cybermen crush the guy's hands. Also, the native aliens of Telos are just creepy with their plastic mustaches and all.
Attack of the Cybermen is my favorite serial of my favorite Doctor. Its a bit violent, but honestly bloody "crushed" hands are fairly tame by todays standards. Some people complain that the 6th Doctor shoots some cybermen, but the Third Doctor killed aliens with a gun, and the 5th Doctor used a gun at least once, too. Its not the most uplifting serial I suppose, but not ever story needs to be happy, upbeat, or end on a good note. Overall, I thought it was a well written, enjoyable story.
