This thread discusses the Content article: Gunslinger Girl + Il Teatrino (Sequel)

Well from the description of the anime I was hyped about it and the fact that it has a second season was even better, however I have to say I was disappointed at first.

Season 1: Season 1 has a bad start and it didn't help that episodes 1 and 2 were pretty much the same save a few extra added scenes. It started to pick up after episode 3 and episode 4 made me watch the whole season. As far as the story goes there is none, yes it is about enchanced girls going around with their "brothers" but unlike One Piece where Luffy is trying to become King of the Pirates overall and in each individual arc beat the main bad guy, or Bleach where Ichigo trying to beat Aizen overall and in the current arc trying to save Inoue there is none of that, each episode is a new mission with no ultimate bad guy to beat at the end as they are all unrelated missions, although it does set the scene in both knowing who the charaters are and from one or two of the missions setting up some the bad guys and storyline for season 2.

Overall I would give season 1 a 2.5/5.

Season 2: Currently ongoing with 3 episodes out at the moment, this had an ok first episode, which was followed up by a good 2nd and 3rd. From the get go a storyline is actually set for the whole season, although it does not become apparent until episode 2; also unlike season 1 which left you with no intrest what so ever between episodes season 2 will leave you wanting to know whats going to happen next, like I am now wanting episode 4 to come out as it is getting intresting now.

At the moment I would give the 2nd season 3/5 but this may change, as for advising people to watch this I'm not sure if I would as while there is nothing really wrong with it there is nothing really good about it either, however I will watch this through to the end none the less.
