I watch a lot of series. I do love a story, especially in evening when I'm brain dead and can't read. If the shows brilliant, I get we have to wait a year - it's a process, there's a whole heap of factors that line up to bring us these shows. It more pisses me off when they get cancelled - like I won't invest in the Sandman now it's been axed.
I just have to quickly watch a plot synopsis on YouTube of the last series or completely watch the whole first season again if it was brilliant (we did this with Top Boy).
I think it's less attention span and more your lack of patience, young lady.
