Ok, as a DC animation fan, this movie really made me go bleeeeh. First, it's hard to take changes in voice after years of getting used to "cannon" but I can forgive it...however, voicing Luthor by the guy who usually voices Gorilla Grodd is bad enough, but making Luthor constantly act a fool is almost unforgivable. This whole story was just kinda weak. Somehow Brainiac, a hyper-intelligent alien computer is "upgraded" by something Lex Labs created is baffling in and of itself! As far as continuity is concerned, this just kinda exists in its own world away from anything prior or afterwards. Doomsday quality it is not. Good thing I bought the Batman Superman Animated movie at the same time to take away the pain from this one. Bleh.
