Right now I'm categorizing all series on the site based on:
Watched = Watched, Rated and have Written a Review For.
Watching = I've watched and Reviewed part of the series.
Stalled = I own the series in full/part but haven't had the chance to Review
Want to Watch = Want to watch based on recomendations, reviews or minor viewing.
Won't Watch = Based on the premise and reviews from trusted reviewers I'm not interested in these series.
Dropped and "1 Episode Watched" = I may be interested in watching the show, but it's currently unavailable in English.
"2 Episodes Watched" = There aren't any relevent reviews to decide if I'd watch the series or not.
I also rate on a scale that might be a little lower than others, as I feel to be rated a 9 or 10 means you really need to have it all, likable characters, an interesting story, great music, and originality. An 8 means it's still a great show, but was possibly just a bit too short or lacked some story/ character developement. I personally think that having 1,250 shows rated between 8 and 9 means ratings around here are way too high (and explains why I've had to struggle through watching some real stinkers that were rated highly.)
