I really don't watch many webseries these days, but here is one with an all female cast from Comediva that I do find entertaining.
It's basically a parody series that takes the form of a reality series where a bunch of BAMF girls (bad*ssmuthaf*ckas) live together in a share house. The girls are all characters from young adult books and TV shows, including Hermione (Harry Potter), Katniss (Hunger Games), Buffy (erm... Buffy), Bella (Twihard), Lisbeth (Girl with the Dragon Tattoo) and Michonne (Walking Dead).
There are some awesome and witty moments throughout the series. It's about a year old with episodes continuing to be released once a month. If you haven't seen it yet and enjoy some of the YA fiction mentioned above, check it out!
