I haven't seen the BRS ova, but the anime, while quite nice and artistic, was nowhere near as good as Puella Magi Madoka Magika, but that's more due to PMMM being a rather excellent anime more than BRS being particularly bad.

Since this is a Nendo thread, perhaps I can recommend some anime based on the Nendos we have available - that's also how I select which animes to watch. "If they make a Nendo from the anime, it must be popular" was the motto I went by, and so far with one exception it hasn't let me down. It also helps that when you end up loving certain characters you can keep them with you beyond the end of the anime, whereas with anime like Nurarihyon no Mago and Rosario Vampire, both of which I enjoyed very much, I'm left pining for a Nendo or Figma which I can keep in memory of my favourite characters. Best to start from the Nendo and work backwards!!

"Stein's Gate" - the cool time-travel series which makes you laugh, cry and sweat almost at the same time. After you've finished it, you can pick up Kurisu Makise and Mayuri Shiina, and there's a Figma Kurisu too. However, if you're like me, you'll end up pining for an Okabe Rintou Figma and Nendo too, but Kurisu is undoubtedly the star of the show, and her Nendo (both versions) and Figma are excellent.

"K-On!" and the sequel "K-On!!" - sheer unbridled cheerful entertainment. The only downer is that there's a HUGE amount of merchandise to spend your cash on after you've finished the anime, so much that it's really scary. It's an amazing series, though, second only to Evangelion Rebuild in terms of Blu-Ray sales when it first came out, I think. The Nendos are also extremely adorable, and come in separate boxes as well as two "live stage" sets which require immense willpower to resist buying!!

"Ore Imoudo .. something". I just call it "OreImo". About a girl who loves Otaku and ropes in her brother to help her indulge in her hobby without letting her friends and family know. That's where the excellent Nendos Kuroneko and Kirino Kousaka come from.

"Tantei Opera Milky Holmes". The exception, but worth a mention because my taste might not be representative of everyone elses, and the four Milky Holmes Nendos have to be the nicest and most colourful set out there - even the five Puella Magi pale in comparison to the bright colours of Sherlock Shillingford, Cordelia Glauca, Hercule Burton and Yuzuwhatever Nero. I hated the series because the four protagonists were just complete idiots (Yui Hirasawa from K-On! was an airhead too, but she had incredible charm and likeability, something which Milky Holmes don't), but the series has a season 2 now, and 4 Nendos, so they must be doing something right!

"The World God Only Knows" is where the demons Haqua and Elsie come from - quite an interesting story about a hero trying to help a demon capture some lost spirits by getting the possessed girls to fall in love with him, and as their hearts fill with love the spirits are forced out as there's no longer any room in the girl for them. The hero was chosen by the demon for help because he plays romance visual novels, and due to that is an expert on theoretical female emotions. Quite interesting, although that last episode was really lame and kind of spoiled it for me. Elsie and Haqua are great Nendos, Elsie in particular has those rapidly-moving arms and legs effects which are just hilarious!

"Sora No Otoshimono" is the one I'm watching now, and the Nendos from there are the Angeloids Ikaros and Nymph. I haven't finished it yet, but so far it's been a really excellent anime. A bit more fanservice than normal compared to other anime in this list but nevertheless it has a good-paced story that slowly draws you in despite a lot of slapstick humour. I'm halfway through season one and I don't even know the main plot yet - but feel like I know Ikaros and Nymph quite well already!

"Working!" and the sequel "Working!!" was decent, and the Nendos Popura, Inami, Yamada as well as the Wagnaria restaurant set are just adorable! The overall theme of Working isn't that great, more about a bunch of restaurant workers who have rather weird habits which become obsessions - the weaknesses are that the habits are a bit over the top (such as a girl who fears men and will hit them within a certain radius with superhuman strength, and a guy who absolutely adores anything small and loses interest when they are larger and less cute), and the episode plots revolve around these silly habits which get annoying after a while. Nevertheless, there are some really good episodes in there, and none of the cast really end up being unlikeable, and there's a certain charm to the series (and I always end up starting to enjoy it just before the series ends =P).

That should tide you over for quite a few weeks or months, and set you on course to have a large number of Nendos to hunt down when you're finished! I'm evil, I guess... welcome to the land of no return!! =)
