If you haven't seen it yet, watch it.
I ended up giving it an 8/10.
I was a bit wary of watching a 50 episode series, as they tend to drag on for no real reason, but I found the show to be enjoyable throughout.
The soundtrack is pretty good, generally pretty spot on for the scene (especially the comedic moments).
Character development is great, with some characters being very noticeably different at the end of the show, while a clear progression is noted as the series goes on.
The animation/art is about what you'd expect from a show that aired ~6 years ago. I particularly enjoyed the animation for the few mind-@#%^ scenes, they did a very good job with those.
Oh, also, while mechas are important to the story, they aren't as emphasized as in a show like Gundam, or TTGL.
