Traditionally, Gundam has always looked at the use of mobile suits for war, and this was no exception. The way that characters were selected and developed as pilots was much different than in previous series. I will not go into detail comparing this to other Gundam series, simply because I don't want to give people the impression that they should stay away from Gundam 00.
In its own respects, there were a lot of elements that made it a good show. The characters that they created were unique in how they interacted with their mobile suits. Having 4 different factions fighting through the war made the dynamics between characters very interesting. I thought that having the Gundam pilots sworn to secrecy about their real identities, even from each other was a good element.
I would recommend watching this show, but be advised not to go in with the anticipation that this will be like the previous Gundam series. I think that going into this show with an open mind will make it a lot more interesting to watch than trying to find comparisons to the originals.
