Eh, they're of their time, but so is everything. Personally I love old suits and think they usually hold up great, and if there's a good story and some kickass action, the costumes/effects don't really matter that much, IMO.
Yeah like the scence in Black where Kotaro and Nobuhiko into Black Sun and Shadowmoon. Always creeps the hell out me. And their will probably some creepy ass scences in Kiva once we get to see his unsealed form.
