Just wrapped up a two week period where I watched all of Gasaraki from start to finish for the first time (well technically not the entire series for the first time since I bought the first few DVDs a few years ago, but didn't get the entire series until this month) and I'm quite pleased with the show, Sunrise turns out yet another great mecha anime. I know I'm quite late regarding the show, since its already been released here in America a few years ago but I would like to see if anyone else has any comments on it.
Various observations:
-With the ridiculously large cast I was expecting a kill em all ending a la Tomino or RahXephon and was pleased to see that they did not take that route in the end, killing off only a few characters. Leaves the show open for a sequel I guess
-Having seen many mecha shows this seems to be about the most realistic one I've seen, in regards to the mecha and their abilities. The creators said in their interview on the extras portion of the DVD that this was what they were trying to accomplish and I'd say they did it with flying colors, nothing I've seen can hold a candle to this show in that regard.
-For all the 'Gasaraki is an Eva ripoff' stuff I've heard in the past few years before I've seen the show in its entirety I've got yet another reason to add to the pile of why that comment is ridiculous regarding all shows. None of the characters were all that similar, even the Rei-Miharu comparison (Miharu's got much more depth to her than Rei can ever hope to and is much hotter

); the robots of course were as far apart as you can get and Gasaraki was way more toned down in the supernatural aspects.
-Was able to figure out that white haired guy was the leader of symbol an episode or two before they actually revealed it to us, certainly helped in part by the fact that both he and the deep voice that talks to Meth which ends up being him vanished throughout the entire middle portion of the series and reappear at the end.
-Great japanese voice cast! Really liked the VAs for Miharu, Misuzu, Ataka and Meth. Now time to try the dub...
-My only big complaint? When Miharu went Key on us for a while late in the series.
