Hard drive space is cheap, my internet doesn't throttle or charge extra for usage, why not get any and everything that strikes my interest? Worst case you don't like it and you delete it.
No, I'd run out space before getting more.
I don't only have anime on my drives...
You gotta lay off the porn, megiod-rev.M.

Gintama ---> hasn't been interesting so far. Watched only two episodes. I will have to decide this for myself if I find the time.
Gintama is basically a gag anime that parodies other Shonen Jump titles and their requisite cliches.
It's very hit or miss.
They even parody non-Shonen Jump titles, such as Yatterman and Detective Conan. Even Jackie Chan, the martial arts star, is parodied in one episode, along with his co-star Sammo Hung. There's also a parody of the legendary tokusatsu show Ultraman.
Gintama basically parodies a lot of stuff.
Another thing you will notice, if you are fan of shows like Naruto, Bleach, and One Piece, is that many of those show's voice actors are the main characters in Gintama. Listen very closely to the voices...
