So where do I start? Well I guess the first thing I can say about myself is I've been a fan of anime for quite a few years now and the first one I watched was pretty much the dubbed version of Inuyasha. Like most people, I grew up with the typical fare as a kid seeing series like Pokemon, Dragonball, Digimon etc on TV then discovered subbed anime on the interwebs and my repertoire expanded in the process.
As for personal taste, I'll watch almost anything but I have a pretty big craving for tragic and depressing stories laced with cynicism, think of Urobuchi's stuff as an example. Although it can't be tragedy just for the sake of it and it has to be well-founded. The only genres I think that are a big turn off for me and find most of the time flat-out boring boil down to Ecchi, Harem, anything to do with Feudal Japan and Mecha. But yeah, all the others are perfectly fair game.
Also, I'm a pretty avid gamer and I especially love visual novels. Some of my favourites there include: The Ace Attourney Series, Zero Escape, Umineko, Corpse Party and the Tales franchise but that's just barely scratching the surface. And finally as a general rule of thumb for me, just about anything made from Atlus is made of win and awesome. Insanely difficult games? I love those to death.
My rating scale:
3.5 stars:Solid entertainment and reccommendable
4.5 stars:Brilliant, very few flaws if any
Basically anything below 3 stars to me fall under the mediocre or god awful category.
