It's evil how you were depressing and funny at the same time, lol.
Through the power of comedy, RongRong teaches us about the less ideal parts of Overwatch. The joke is just displayed so matter-of-factly, and I think that's what makes a lot of this video so funny. Like, "here you go, this is the messed up part. Now enjoy the laughs."
The creator also doesn't have to necessarily dramatize anything, while still being funny. It's not the easiest thing to pull off, especially with an E rating, so props for that.
I like how I can relate to what the video is showing me, yet also makes me think. Like, "Okay, we all apparently know about these messed up things, but it to a comedic video to point it all out? Conspiracy much?" lol only half joking.
For me personally, the creator's "crazy" moments were most effective because they were given sparingly. It wasn't the major tone of the video, so not too much, which made me appreciate them more.
This is my first time watching any of his videos. So as for possible rooms for improvement? If he hasn't already, one of the two options for future projects: voice actors, or adding his unique, witty lines about a subject. I saw a glimpse (literally lol) of the latter in this video. Maybe see if he has any insightful commentary or jokes to offer.
Solid work, friend :)
