Saying that the characters make horrible mistakes or that plot points don't make sense is missing the point of the Parody. This would be like lambasting Madoka magica for it's somewhat weird explanation of why magical girls exist. Or blaming Konosuba for the failings of the party on their quest to kill the demon lord. Too many people are missing the point of Fulldive, it's by no means a masterpiece but it is certainly passable for what it's attempiting.
Fulldive is a decent parody that has some genuinely funny jokes that are material for long running memes. It points out how realism in gaming is not necessarily good and how bad a pain system in a game would be.
In short Fulldive is a pretty decent show for what it's trying to do, and everyone understand this simply doesn't remember the promise we made under the tree and will be forever stuck in Martin time.
