I have no problem with people enjoying the more comedic style found on That Guy with the Glasses but to me, it seems like an old trope that lost it’s appeal quickly. It worked great at first, but so many people latched on to it and try to force humor by making fun of bad movies / videog games / tv shows it quickly became old. More importantly, comedy is just icing. It’s there to supplement the actual substance; the analysis and information we can find. It’s the same reason so many people disliked Double Rainboom, all comedy with little substance.
Nostalgia Critic and AVGN understood that, wich is why they gradually included more serious analysis in their videos. The question of how much icing, or comedy, is needed in a review is clearly a question of preference. I find that a lot of internet reviewers ruin what would be a great review by forcing comedy. Linkara is the best example that comes to mind. Good reviewer, horrible comedian.
SF Debris is easily my favorite internet reviewer. He’ll focus first and foremost on reviewing the episode of the week and will only put in jokes when they come in naturally. Some reviews are more opened to comedy then others. It’s a question of balance.
