I have to be honest. When Gossip Girl was renewed for its fifth season I wasn't sure at the beginning. The first half of the fourth season was amazing and then it became bad at the ending (reason of why the show lost a lot of viewers).
But who doesn't love Gossip Girl? I mean, it's one of the most sassy TV series ever. Betrayal, secrets, and more... just at the GG style. The fifth season introduces us to a lot of new plots (and not recycled ones), like Charlie protecting her real identity, Serena working on the movie business, Dan finally getting his book published and Blair preparing her royal wedding. I just think this season made us see a different side of the characters, because they are more mature now, but that doesn't mean that they decisions take the wrong way, why? Because that's what makes a show good: the twists.
Most people say that the show is just getting worst by every episode, but I truly still enjoy it. If you stopped watching the show, watch the fifth season, maybe it could change your mind. There's another perspective, but a good one.
It's worth the pre-order, and I hope it has a lot of bonus features (the most fun part of this kind of box sets!)
