- Critical Dissonance: Being a critic, he often receives letters from listeners who disagree with him, but there are two big examples where a majority of correspondents voiced their disapproval.
- The Greatest Showman. In his review, he described it as a "very poor" film that "rang terribly hollow". His opinion of the film improved somewhat when, having listened to what other people had to say about it, he paid to see it a second time and saw the uplifting effect that it had on his fellow cinema-goers.
- To an even greater degree, Deadpool 2. While he loved the freshness and self-aware humour of the original Deadpool, he disliked the attempts to flesh out the character, seemingly unaware that Deadpool has had plenty of deep character moments throughout his history.
- He Panned It, Now He Sucks!:
- He suffers this constantly, most prominently with the Pirates of the Caribbean movies, saying Superbad wasn't very funny, and being disappointed by Watchmen, not even a panning, just saying the movie didn't work for him personally.
- Inversely, he gets huge amounts of "He Praised It Now He Sucks" for taking a liking to movie series such as High School Musical and Twilight. He was even a fan of Zac Efron, until he starred in the abomination that was Dirty Grandpa.
- Just Here for Godzilla: Some just watch his reviews in hope of him going ballistic on a bad movie.
- Memetic Mutation:
- Hello to Jason Isaacs! The phrase appears at the start of search results for Jason on Google UK and has also popped up in graphics on Letterman, amongst other places.
- The throway line in The Thick of It about him having massive hands.
- Nausea Fuel: The "vulgar, saccharine horror" of New Year's Eve had this effect on him.
- In the review of Marley & Me, Mark makes the film sound so sickly and sweet that his description might actually make one feel unwell.
- The Moshi Monsters review gives a similar impression. He actually likens it to sticking your head into a waste disposal unit full of vomit.
- So Bad, It's Good: Occasionally his opinion on a film is this; for example Pompeii "laughably stupid, but I don't say that as a bad thing because heaven knows there are enough films that are boringly stupid", and Mamma Mia! (and especially Pierce Brosnan's singing) "you know what this is actually really good, although it's not, please don't put that on the poster. Unless you put 'so terrible it's actually brilliant'".
- Tear Jerker: For Mark, quite a few films, apparently. And listeners' emails on Toy Story 3.
