The main entry for this weeks list has to be Sherlock Holmes; with Robert Downey Jr. as Holmes, Jude Law as Watson, and Rachel McAdams as Irene Adler, this was the Steampunk treat of the holiday season. If you happen to pick up your copy on Blu-Ray and have a BD-Ready player online and a web browser connected to the internet (so you can ask questions), you can join the live event on April 1st and hear Downey answer your questions about the movie.
On the Anime front, Negima? Season 2 appears to be a bit different than season 1, which to my mind expands the range of the show. It still has all the magic, but not as many sneezes.
There is a new entry in the US-released Lupin the 3rd collection, Lupin the 3rd Episode 0: First Contact. It has been a while since the last new episode we have gotten, and the fact that it is Subbed rather than Dubbed indicates the new North American distributor may be an independent operation.
And then there are Strike Witches, an elite aerial combat team that blasts aliens out of the sky, wearing propeller boots and wielding weapons, but with one rather noticeable missing item.
Other releases worth noting include Neo Angelique: Abyss and Six Strange Tales of Liao Zhai 2. There are also a few Complete Collection releases that had previously released each season as a box set, like Aquarion, Kannon, and Otogi Zoshi.
