Nothing beats gathering a group of friends and watching some shitty anime. You should do it too!
If I don't get around to your message in a reasonable amount of time, I'm working on it. I'm like this in the buddy groups too so don't fret.
Ratings and crap:
5 stars - Perfection, or has enough perfect parts to be just about perfect.
4.5 - Just falls short of perfection, or is extremely awesome.
4 - This is the average, which means I either like what I watch because I only pick the good shit or have no real conception of rating things on a proper school-based grading scale in terms of C- to B+ or what have you. It kinda falls apart for another few grade points.
3.5 - Spiffy, but flawed.
3 - Eh.
2.5 - Meh.
2 - Meeeeeeeh
1.5 - Fuck this shit.
1 - Fuck this fucking ass shit.
0.5 - [Retracted from being too profane]
One of these days I have to go through my rated anime/manga lists and reevaluate the numbers and shit, because 5/10 is suppose to be average or middle-of-the-road. Someday... Until then, I'll be slapping shows with 4 stars.
