I didn't think much of 0079 (and Gundam in general) when I first started watching it, but by the end of the series I got so into it that I ended up rewatching the last few episodes several times. I love Kai, Sayla, and Char, and many of the other characters were great too.
Not completely sure how I feel about 08th MS Team yet, but it's interesting enough. The focus on average soldiers is nice for a change, it makes the characters somewhat more relatable. Also the occasional action scenes look amazing.
