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.
In the Jirachi Wish Maker review, he declares Hypnosis doesn't work on Dark Pokemon, which it in fact does.
This mistake was so dumb, even he made fun of it later on in the Lucario and the Mystery of Mew review.
The thing is he usually would be right because in the Generation 6 games, Absol would likely be a Mega Absol which has Magic Bounce which would reflect the Hypnosis.
Ensemble Darkhorse: In the beginning, the Hero had a low-quality camera, clearly read from a script, and at first didn't even have a real personality — yet somehow, on the TGWTG forums and in his later videos, his views are almost even with Diamanda Hagan. To be fair, though, he did fix those problems later.
He Really Can Act: In the Tales of Symphonia review, he starts off on the verge of tears due to Six's death in the previous episode. And for some audience members, his delivery got them choked up as well.
Inferred Holocaust: One apparently happened in the future Number Six came from. We even hear the last few moments of numbers 7-9...
Internet Backdraft: A small contingency of people HATE his "Top 10 Cartoons I Hate That Everyone Else Loves" list.
Special Effects Failure: During the In Search of the Titanic (a.k.a. Tentacolino) review, there's a flash when the Cartoon Villain kills Nina Galas/alternate good Diamanda Hagan but it's not until a second later that you hear the explosion.
