Black Lagoon: Roberta's Blood Trail-Episodes 1-5 (Complete)
I do think this was better than the Japan arc from The Second Barrage, but I can't help but feel it suffered from a similar problem in that it just felt too long. If you trimmed the fat and simplified it a bit, you could have easily told this story in 3 episodes, I think. For example, episode 2 mostly consisted of Rock going around getting info on Roberta, which didn't need to be a whole episode. I also thought the stuff with the various Mafia famlies getting involved got too much screen time and could have been whittled down. Still, this arc still had it's moments, the showdown with Robetera in Roanapur and the Jungle were both excellent.
Sound! Euphonium Season 2-Episode 4
Yet another great episode. I do wonder what the focus of the show will be now seeing as I'm pretty sure the whole Nozomi thing is just about resolved now.
Mahou Shoujo Nante Mou Ii Desu Kara. 2nd Season-Episode 4
Little Witch Academia: The Enchanted Parade
Even better than the first one, absolutely adored this! I liked how it expanded the world a bit as well as giving a little bit more depth to it's characters, not to mention using the longer running time to provide a better story than the first time around. The animation was gorgeous as I expected and I loved how the finale just went full Gurren Lagann at the end for a bit. I honestly think I could recommend both of these shorts to anyone, it has just such a fun spirit that I think the appeal is nigh on universal. I'd definitely like a UK release of both of these at some point.
