My favorite genre is something I don't know a name for; I call it "Awesomeism". It's that increasingly popular thing among people that grew up on toyetic culture where the universe is infested with the old genres--there's ninjas, robots, magic, Dracula (sometimes other vampires too, but always Dracula), and so on. I really think it has to do with our generation having grown up on "action cartoon" as a favorite genre, instead of "Western" or "sci fi", so on any given Saturday morning, we'd watch mutant mammal alien cowboys ("Wild West Cowboys of Moo Mesa"), robot-killing ninja turtles that sometimes travelled through time, cars and airplanes that turned into giant robots, and whatever the hell was going on with Masters of the Universe--cyborg skeletons, naked guys with magic swords, and an oddly Lovecraft-ish backstory about snake-men from beyond.
Now WHY do I believe this genre is the best? It's fun. I hate melodrama, and I like mashed-up genres. The world is too backed up with tropes these days, and I like seeing them getting, as the website says, averted, subverted, and lampshaded--half the time I can predict right where a plot is going once it's been set up, so I like to see things that can either have fun doing it or play with the notions to create something new.
And now we're the ones leading the entertainment industry. "Dr. McNinja" is probably the most famous example of this genre, although "Axe Cop" is up there too; some of the wackier D&D strips do it as well. I'm on the lookout for others, and if you agree with any of what I just said, then you should probably go ahead and click my banner ad for my own comic.
