Comet Lucifer - Dropped after two episodes. This doesn't look like its doing ANYTHING unique or to distinguish it from a thousand other "boy meets weird girl and gets a mecha" shows.
Concerto Revolution - The most recent episode was the best one yet. The eaiset to follow and some sweet sakuga action at the end. Hopefully the show is on an upwards trajectory.
Lupin III 2015 - Pretty much what I expected - aka good, clean, enjoyable anime fun. Episode 4 was kind of weird though and people in this show have an uncanny ability to dodge bullets. Still this is classic Lupin and I'm enjoying myself.
Gundam Iron-Blooded Orphans holding steady and doing better than I expected. I was afraid Mika was going to be one of those no-emotion robots but I think they've done a good job of making a character who is more reserved and stoic but not coming off as some robot.
One Punch Man continues to be God's gift to anime and anime fans <3
On a side note, what are you guys doing? You have total control of the anime you can watch and y'all spending your time watching shitty battle school shows
