Critic's small, whimpery "no" when Ma-Ti... leaves. Even more heartbreaking 'cos you expect an hilarious, melodramatic Big "NO!" to break up the sad.
Also when he comes back into his house at the end and sees the coffee Ma-Ti fetched him sitting on the counter. The look on his face just breaks your heart.
Even moreso during the ending montage where 'everyone was reviewing like usual', cut to Spoony trying to review Final Fantasy XIII... and stops just to scream "MA-TIIIIII!!!!" with the most heart-wrenching face he could muster.
Critic sitting by Ma-Ti's body, his glasses off, his tie gone and looking completely and crushed.
Seconded. If you sympathized with the Critic at the end of Kickassia, he was at least still wearing his glasses (albeit broken) and snarking, and you could take comfort in the knowledge that he wasn't fully broken. Here, he's completely vulnerable.
It might sound weird, but the fact that he's still sitting in a kinda girly way just makes it worse.
Also serving as a heartwarming moment, Critic kissing the Quaker Oats can at the funeral. Fuck how he treated Ma-Ti earlier, boy desperately needed a hug.
At the funeral, Sage has tears in his eyes. Let me say that again: Sage—the only person who can scare Ask That Guy—is crying. Sage even said in the commentary that he got into a bad place so he could make the tears real.
Also at the funeral, Chick clinging to Jew Wario like she might fall apart if he lets go of her.
Ma-Ti still got the Critic his coffee. Why is my screen going swimmy?
Even Lewis and Liz say in their commentary it's like a final stab in the gut.
The "from Ma-Ti" written on the coffee cup. It was probably just done to make the scene more clear, but it's still sad in a touching kind of way that Ma-Ti took a minute to leave the Critic a note.
Critic lying on his bed alone, having no energy to do anything or even go back to his usual clothes. (Giving more credence to the "It's All My Fault so I don't want to wear my Iconic Outfit" theory up above.)
"Linkara... do you ever think we'll see Ma-Ti again?" God...he sounds so hopeful, almost like a little kid (and coming from such a broken, cynical guy, that's really saying something).
Even though he gets saved both times, Critic being willing to let Jaffers kill him when he still had ample opportunity to run away (unlike Kickassia where he was trapped against a fridge) just doesn't sit right.
The rockiness just fades out into something sadder and slower, mirroring the story.
"I don't want to end this way/in our flight of fantasy/stand by my side/it will be okay..."
In Benzaie's VLog, Doug's speech thanking everyone for getting through the shoot and convincing him not to cancel it. Heartwarming because he cares so much for them (and vice versa), Tear Jerker because hearing DougWalker struggling not to cry is unsettling.
The DVD making-of featurette shows the whole meeting between Doug, Rob, and Mike Michaud as they realize the film will very likely not be completed, and they should just do a Lost in La Mancha style documentary about their attempts to make it. Even knowing everything turned out fine, it's very hard to watch as they decide to scrap their labor of love.
Doug revealing that he got so miserable by the middle of the shoot that he spent a day in bed making calls - not even eating, showering or brushing his teeth - was pretty woobie-ish too.
And when he's recalling this (still sounding actually kinda upset), you see a sad little lump in the middle of his bed. Poor boy.
The two DVD Commentaries from Doug and Rob will make you want to hug them both. In Doug's, the first twenty minutes is him positive he's ruined everything and that anyone who does crossovers with him just wants to be polite, while Rob goes into more detail of Doug's nervous breakdown (he wasn't even going to show up to the Holly-enforced meeting because he was so scared) while admitting that for his part, he had an urge once to go into the forest and never come back because nobody would miss him.
Rob's pride in Doug realizing he just can't do everything alone becomes much harsher after "The Review Must Go On", where Doug decides it's right for him to be alone because nobody can keep up with him.
Even knowing that everything ended up working may make it even worse. Seeing just how close the special came to being scrapped makes everything really depressing in hindsight and can make it kind of hard to watch.
We get more Jerkass Woobie-dom from the Critic in the search for the Necronomicon. While he needs a slap for how he treats Chester, it's made incredibly clear that there's no way he's moving on from Ma-Ti's death.
And if you've ever tried to give up something addictive, you'll know (despite his looking around in a haunted house) how Chester is feeling when he's forced to be sober and is telling Critic he's in a world of hell.
Malachite is still alive. Bargo left the site in February and unless they're doing a Suede-type thing, will never come back. It just makes Ma-Ti's sacrifice and Critic's broken denial over it so very pointless.
