The most underrated anime of all time in my eyes is Little Busters!. It would be my favorite anime if it weren't for Steins;Gate's nostalgia. People overlook it in favor of other Key anime like Clannad and Angel Beats, especially since the best part of Little Busters is the end, which doesn't happen until thirty something episodes in (Not to say the rest isn't phenomenal as well). But rest assured, it's absolutely amazing. Watch it. It's on Crunchyroll.
