Each season is so dramatically different from the other, its as if you're watching 3 separate shows.
The first season: It's immediately clear this show was created by youtubers. It's funny, irreverent, yet lacking the capability to deal with real substance.
The second season: It contains all the humor and quirk that made the first season enjoyable to watch, yet there are issues delicately woven in. Relationships, parents, and friendship are explored, without the show feeling contrived or fake. Personally, this is my favorite season.
The third season: I never would have thought in a million years that a show titled Video Game High School could ever carry so much emotional weight. It's character-driven story line is poignantly realistic, yet I feel remorse over what the show use to be. I watched the first and second seasons because they were fun. They were funny, but not How-I- Met-Your-Mother funny, with one liners and punchlines. It was the kind of fun everyone has experienced, the casual yet incomparable fun with friends that makes one forget life exists outside of that moment. However this feeling is absent in the third season. The fate of the characters doesn't seem so concrete and certain. Maybe things don't turn out alright. Maybe they never will. The characters fall prey to real- world issues. And while these issues are explored fantastically, I still find myself missing when I could sit down, turn on the TV, and know I was in for a barrel of laughs.
