Just saw Blade and Nexus eps 1...(and Ultimate Girls and God Mars eps 1...I'm on an ep 1 kick today I guess) -- I loved both, but in some ways, Blade and Faiz balance out. I was actually able to keep track of what was going on in Faiz a little better, even though Blade's was revved up a lot higher; Kenzaki's drama was pretty good, but IMO Yuji's felt more drastic (but then, I tend to like Yuji's actor).
Nexus ep 1 was very interesting as a story and etc. setup; lot of fun watching the latest paramilitary team go running about, and great ep, but it didn't make it to being on my Yay Best First Ep Evarrrr list. GranSazer is at about the same level.
