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.
YMMV: The Gamers
Big Lipped Alligator Moment - Ninjas delivering pizzas fighting against pirates in the Wizards of the Coast office was awesome, and had absolutely nothing to do with the rest of the movie.
Designated Hero: We're supposed to sympathize with Lodge, and yet he does several things that show him to be a terrible DM. He chronically railroads, he arbitrarily takes away player character's powers (something which the DM guide specifically says you should never do), he throws a monster at the party that can mind control the entire party with no save, and he introduces an NPC specifically to babysit the PCs while keeping them on rails. Cass's actions (bitching him out over the TPK at the start of the movie, pulling all the modern items out of the bag of holding) seem more like the actions of a frustrated player trying to take some control over his character than those of a whiny munchkin.
However it could be argued that the film is just as much about the growth of the DM as the players. When the film starts Lodge is visibly high-strung and kind of a jerk himself. He also makes bad decisions, resulting in two TP Ks (one of which is stated to have taken place before the film began), and adds a Paladin GMPC to the game, mainly to keep the players on the railroad. As the story progresses he becomes more lenient, allowing the players to get away with some of their more morally questionable actions, letting Cass use a lightsaber and shotgun and taking the powers away from his Paladin who doesn't need to rely on them as much as a Cleric. Note also, that Lodge's entire motive is to make the adventure one that is PUBLISHABLE, which explains his focus on story. (If the players break the adventure, he can't publish it.)
Jerkass Woobie: Poor Cass seems to have some deep-seated control issues.
Why would Cass invite Joanna to the gaming group? Why would he make a Fanservice character in a Chainmail Bikini for her to play? Almost as if he's still into her... oh. Oh.
Nightmare Fuel: In Hands of Fate, Myriad's climactic confrontation with undead Dundareel is incredibly creepy.
Romantic Plot Tumor: In the extended version of Hands of Fate Lodge and Joanna have extended relationship troubles that have no impact on the core story. In the regular cut it was completely removed without a trace.
Why Fandom Can't Have Nice Things: In-universe The Legacy are trying to do this on purpose, trying to kill everything about the game that makes it unique in hopes his will drive out the storyline fans and open it to pro tournaments instead of ones that control the plot.
