Summer 2010 wasn't an especially good season of anime:
Major season six > Asobi ni Iku yo! > Strike Witches 2 > Detective Conan (579-590) > Seitokai Yakuin Domo > Shiki (1-11) > Amagami SS (1-13) > Heartcatch Precure! (20-33) > Shukufuku no Campanella.
Dropped: Legend of the Legendary Heroes (1) | Worse than Cosprayers: Ookami-san to Shichinin no Nakama-tachi (5) > Mitsudomoe (1).
Major was easily my favorite show from summer 2010, although I felt the "yips" arc went on too long.
This was my favorite part of the OP.
Asobi ni Iku yo! was a lot better than I was expecting. It stayed fun the whole way through, but I would have liked to see more of the evil-type Momiji. And they never explained what the deal was with her older younger sister.
Not this shit again.
To some degree, I enjoyed the second Strike Witches season more than the first one. Nevertheless, it really did feel like a re-hash of the first season.
Detective Conan is Detective Conan. I continue to enjoy it as I plow through the hundreds of unwatched episodes I have remaining. As you can see, I've long since realized there are no meaningful spoilers in Detective Conan, so I've started watching the currently airing episodes along with my backlog of older ones.
The rules segments with the drum and whistle were my favorite parts.
I really enjoyed Seitokai Yakuin Domo and its relentless stream of sex jokes and short jokes. It was probably funnier to native speakers, though; it's tough to adapt verbal comedy to different languages.
Shiki hit a long skid of tedious episodes, but the recent ones are quite good, especially if you enjoy hollering directions to idiot B-movie characters. E.g., "Don't go in there!"
Amagami SS is pure cheese. That said, I still look forward quite a bit to each new episode as Potato-kun attempts to trophy-love every girl in the school.
Obi-Wan Kenobi supplants Tart as the least annoying Precure mascot.
I'm still not a huge fan of Heartcatch Precure! but it is growing on me.
Shukufuku no Campanella kinda sucked, but all the scenes with the Tortilla sisters or Agnes made it worth it. Also, "ARMAGEDDON JA YO!"
I tried watching Legend of the Legendary Heroes which I figured would be tongue-in-cheek, but it wasn't very interesting. Dropped after one episode.
Now, two shows I not only dropped but considered to be, ahem, WORSE THAN COSPRAYERS: Ookami-san to Shichinin no Nakama-tachi was inexcusably terrible. How J.C. Staff fucked this up, I have no idea. I dragged my way through five episodes. Finally, I realize I'm in the minority in not enjoying Mitsudomoe, but the only thing I saw in the one episode I managed to watch was ugly children doing horrid things.
