Looking through the threads, it seems that a lot of you want a complete collection when you buy a TV series and that you would hesitate to buy if the whole series would not be released. There are some long-running shows that I will gladly buy every season (Buffy, Futurama, Alias, a few others). But my budget is limited and frankly, some shows just aren't worth investing in the whole series. For instance, I will probably buy the fourth and fifth seasons of The X-Files eventually, and maybe one or two of the earlier seasons. But that's as far as I'll go given that the quality seemed lower in the later seasons and the price. I bought the first season of Charlie's Angels and may buy one more, but two sets seem like enough to fill my appetite for the show. All five seasons would be overkill. So how about you? Do you go for one season, some seasons, or are you a true collector who wants every season?
