I'm glad that you added that first word, as opposed to your first post about SM....otherwise you might have been beaten to a bloddy forum-like pulp by a few here...
I really like Full Metal Panic and it's 2nd season, Full Metal Panic: The Second Raid. One of the best anime shows you'll ever see.
First it starts out with mechs and girliness, but at the end of TSR suicide, murder, and hopelessness are greatly hinted at. It's such a great anime because the characters actually think...you find yourself saying "oh, i wonder if she'll do that" and then you see them ponder it onscreen and follow through. Most shows like Pokemon and any other horrible american transitions almost always lack character thought...and this makes this anime the only 6/5 in my books (with a few others getting a perfect 5/5, but I won't list them here).
Sadly, there aren't any full copies of TSR out yet in english (only the first dvd of 5), but the entire first season is out in a DVD boxset...
If you wanna give it a shot, check it out here (subbed):
