I don't try new animes on a whim.
Only if they're new adaptations I'm familiar with in one way or another, for me solo.
Other than that, I watch a lot of review shows and if I hear good things about something new, from either a critic or friend, then I'll also check them out.
Apart from that, new anime doesn't particularly interest me. The biz is in the toilet right now.
So you never just explore what is available for the fun of it?
You know the whole three episode rule deal or studio hounding.
Watching anime isn't a priority anymore. I have other things to do.
Sites like MAL have grossly inaccurate ratings, reviews, etc, hence why I prefer word of mouth to be from one trusted source.
I forgot to mention too, I'll watch animes given to me by friends or whatever, even if they just pick them out on a whim for me.
I've actually found a lot if great stuff like that, including my favorite anime series of all time, Shakugan No Shana, because I never would've checked them out otherwise, and they're too obscure to be on review series.
But that's life, really. Luck of the draw. Right place, right time.
