Hi everyone! I only really got into anime pretty recently, in roughly April 2012. I haven't watched all that much at the moment. I started with Shinryaku! Ika Musume followed by The Melancholy of Haruhi Suzumiya based on recommendations, and have discovered many more thanks to this site. Nice to meet you all!
My rating system is based on how much I personally enjoyed the anime as a whole, not its components, and is as follows: 0.5-1 star = It was terrible. 1.5 stars = it was bad. 2 stars = it was poor. 2.5 stars = it was unimpressive. 3 stars = it was OK. 3.5 stars = it was good. 4 stars = it was really good. 4.5 stars = near enough a 5 but with something holding it back. 5 = it was seriously enjoyable/masterfully done.
I also aim to have 0 anime ever listed as Won't Watch to stay as open-minded as possible, and to never drop an anime no matter how bad it is so I can make a proper opinion of it when it's finished.
