For years, people have praised this as one of the best classic serials, one of the best 4th Doctor stories, a breakthrough in storytelling. I just don't get it. In the 6 or so years i've owned the DVD, i've seen it maybe 4 times, trying to love this story like everybody else but it just doesn't get me. Episodes 1-3 drag, with some good moments mixed in with the boring stuff, Tardis scenes are a highlight, "I'm not a human being, I walk an eternity" and going to see the future in Suhtek's timeline.
Episode 4 is great, it has atmosphere, the stuff between the Doctor and Suhtek is spot on and the Doctor really does feel like an ant before Suhtek's power.
Gabriel Woolf as Suhtek is phenominal and can see why he was brought back for Big Finish and for the New Series as the Beast in series 2.
4 and Sarah Jane are on typical form, some great moments from them.
Overall I just find the Pyramids of Mars to be a very overrated story that I just don't click with like others do :/

Ambassadors of Death has the unfortunate experience of being the really weak story sandwhiched in the otherwise terrific season 7. All the other stories range from very good (Spearhead) to really fantastic (Silurians.) Its a damn shame too, because this story isn’t dreadful by any means, it just suffers heavily from some very clear last minute rewrites that do nothing but muddle the whole affair. The beginning of the story is very strong, but it continues to add new elements that never go anywhere, and the ending just sort of… stops. The motivations are either contrived, predictable, or nonexistent, and the plot fails to give our main characters anything meaningful to do. But hey, the aliens are actually quite well realized.

To me, this is Doctor Who at its best. Its weird. Its wonderful. Its scary. Its thought-provoking. Its intense. Its visually captivating. It’s a beautiful blend of genres: the “alien invasion” and the “temple exploration” movie. Troughton is amazing to watch as the Doctor and delivers some simply iconic lines in this episode. The Cybermen are scary and exemplify just what makes them some of the best monsters Doctor Who has ever had. Absolutely terrifying and captivating at the same time, and completely rewatchable.

Perfect. Absolutely perfect. I know the complaints: “Its too dark, its too grim, its too action packed.” I don’t care. This episode to me ranks as one of the best, and about as perfect as Doctor Who can get. The Doctor and Peri land on a mysterious planet and quickly get tangled up in a political and commercial conspiracies. And, to top it all off, the Doctor knows he’s going to die the entire time. I mean seriously, what a great setup/setting for a story. The rest of the episode is him struggling to make his last moments count. The characters are complex and layered, and the Doctor is heroic and cunning - exactly what the 5th Doctor SHOULD be. This episode makes your hairs stand on end and your spine tingle with fear. Perfect perfect perfect.
