It depends. Sometimes I really learn all the words before watching, sometimes I just watch something without any preparation.

Adding too many words to Pleco SRS over a short time doesn't work well, you will get overwhelmed with reviews quickly. So if I decide to study the words for a tv show I take some time between the episodes to prepare for the next ones, depending on how many words I have to learn it could be days or weeks.
