I have nothing better to do.
Already having a decent amount of anime under my belt from my (non-otaku) childhood, my anime 'career' started when I tried to finish a list of shows compiled by my friends during the summer. The list ended up growing faster than I could keep up with (with me searching around and finding stuff to add on my own), and I continued to watch anime regularly. After joining a couple of anime clubs/societies, I became aware of the more current stuff airing in Japan.
Here is a quick link to shows I've recently completed watching (does not include stalled, "almost complete", etc.).
My rating system (out of 10):
1=unwatchable, 2=shit, 3=bad, 4=poor, 5=mediocre/average, 6=OK/entertaining, 7=good/enjoyable, 8=great/solid, 9=amazing/flawless, 10=exceptional/masterpiece
So, for example, a show I rated 3.5 stars is 'good' in my opinion. This doesn't necessary reflect how much I enjoyed the show, but more how good I think the show is on paper, how it presents itself, and how close it comes to hitting its intended target, relatively. Good writing and storytelling, compelling characters and easy to follow pacing will raise a show's score, and some criteria (such as humor) will affect certain shows' ratings more than others. Inconsistency willl also affect the score of a show: a show that seems poor at the beginning, but gets better toward the end may score better than a show that seems great at the beginning, but tanks hard.
I didn't rate shows that I felt I couldn't fairly judge (ie. shows I watched a long time ago and don't remember vividly). Here's a quick link to my rated shows auto-sorted from highest to lowest. Shows aren't sorted within the same star rating.
*Note for The Melancholy of Haruhi Suzumiya [(2009)]: This website contains the entire 28-episode ("season 1"+"season2") release as one anime, whereas MAL only contains "season 1" and "season 2" pages (with only season 2 being listed as from the 2009 release). I'm only watching the 2009 release, but I've decided to rate "season 1" and "season 2" separately. My rating for the first 14 episodes is listed on the 'dropped' 2006 listing, and my rating for the latter 14 episodes will be listed on the 'watched' 2009 listing, although I will only keep track of episode progress on the latter.
