These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
General Kala's outlandish outfits and strange body language remind one quite a bit of Lady Gaga. They even look a little alike. Considering that Lady Gaga's stage name comes from a Queen song...it's enough to blow your mind.
The same joke was repeated when he was the guest host the week Thatcher died.
Someone writing in a newspaper in the UK hoped there would be an election while Sir Menzies "Ming" Campbell was leader of the Liberal Democrats, just because that would make it "Ming vs. Gordon." Sir Menzies was called "Ming the Merciless" and compared to him on occasions.
Ming is hypnotizing Dale Arden with his ring and causing her to writhe in a sexy, sensual manner.
Ming: Did you ever see such response?
Klytus: No, truly. She even rivals your daughter.
Tear Jerker: Flash and Dale's conversation before his execution; the music only adds to it.
They Wasted a Perfectly Good Plot: For some, the Flash Gordon property deserves a better made, more serious take than this. If the intent was to follow in the steps of Star Wars (which was inspired by Flash Gordon, among many others), why couldn't they have made it more like Star Wars?!
Alas, Poor Villain: Lillian, from the episode "Life Source". At first, she's a standard Monster of the Week, draining Earthmen for their life force. Then we find out that she was picked by Ming to drain the life from others to keep him alive, and at the end, he drains her completely and she crumbles into a pile of dust.
Crowning Music of Awesome: The commercials for the show featured a great cover of Queen's theme song done by indy band Louis XIV. Unfortunately, said cover never made it into the show.
