Any time Phelous shows that he can do better effects than the movie he's reviewing.
My personal favorite being when he parodies the gratuitous chroma key in Pulse 2.
Because so little happens in The Time Machine (I Bought At A Yard Sale) and the green-screening is so bad, nearly half of the review is devoted to Phelous imitating its use of Google Image screenshots for backgrounds. It's impressive how much better he is at it (thanks to things like "lighting" and "proper understanding of how to edit a film").
And now he's made the intro even better, matching the opening to the new series.
Related to both above, Phelous reenacts the entire plot of Triangle in his review for it, and manages to be both creepier and make more sense than the movie itself.
The performance of the Darkwing Duck theme in the end of Cry_wolf. Especially awesome for those who grew up with Darkwing Duck.
Shooting the DVD and case of Resident Evil: Afterlife. He manages to shoot the disk dead center!
YOU'RE AN ALICE SANDWICH!
His review on A Serbian Film, in which Phelous, who had previously watched The Human Centipede without flinching, actually included a warning for the disturbing scenes he could actually show, before proceeding to violently eviscerate the film for its grotesque imagery and supposed message behind it. His utter rage is absolutely justified.
Phelous: I know I'm really falling into the angry reviewer thing on this video; well, that's exactly how I feel about this movie!
The ending skit of his "Five Across the Eyes" review should count as he perfectly parodies the movie by sitting in his car, whining and crying, and flailing the camera about for a goodminute and 34 seconds.
Phelous: I know a lot of people like violence in media like in Videogames and Movies but unless you're an asshole who can't tell the difference between real violence and fictional violence we don't need a movie wagging its finger at us and thinking it's so clever for doing so."
In his review of Lockjaw, Phelous redirects a line from a Designated Hero who called out the antagonist for murdering her friends in revenge for them accidentally running over his wife (even though they ran over her and just passed it off as an animal without a second thought)
Phelous' brutal calling out of Wrong Turn 5, from the Idiot Plot to the pointless scenes to the Karma Houdini moment. He goes as far as to predict that the sequels will involve the Hillbillies going into space and killing the aliens despite the aliens having the superior firepower.
