You know for me, it's seasonal.
I tend to watch more anime when it's colder cause I can stay in my room all cozy like.
I watch less in the summer cause I want to save money and not have the air on all the time.
And when I do watch, it depends on how good a series is.
If its really good I watch it with a week or two.
And if it's not so good... it can take me months.
It took me almost a year to get trough Saiyuki.
