I loooved it. Adorable! It was fantastic with the exception of Captain Hammer. I love Nathan Fillion, but I felt like Hammer was too over the top, though it wasn't entirely his fault. Joss was a little heavy-handed with the silliness for Hammer, and I didn't feel like he fit into the show the same way the other characters did. I didn't care for Hammer. But I looooooooved Neil Patrick Harris as Dr Horrible, and Felicia Day was adorable, too. And everyone else involved in Horrible was like a little Joss Whedon yearbook, with the costume designer from Firefly, and David Fury and Marti Noxon as the anchorpeople (they were executives on Buffy and Angel). Yays. Loved it. Dr Horrible <3.
