There isnt really any show that I'm literally scared to watch, however if its a show that I know Im going to love, I prefer to avoid it untill all the episodes are released so I am not constrained to 1 episode per week. (Sadly I couldnt resist on Code Geass and am now stuck with the one ep per week blues on that one
) I did manage to hold off on Macross Frontier though as I havent watched past the first two eps of that and I'm eagerly awaiting its completion so I can marathon it.
