Godzilla Vs Godzilla?

For the legendary series (if there is one), yes it's ridiculous. But if it were apart of a toho series then yes it's a good idea.

Legendary, as far as I'm aware, is trying to keep the movie(s) rather realistic, as far as Godzilla can be considered realistic. So, I don't think we'll see a Godzilla v. Godzilla movie anytime soon. Besides, I think the GMK suit is already deteriorating. So, unless they remake it, I don't think Godzilla from GMK will be in anymore Godzilla films on TOHO's part, much less Godzilla v. Godzilla. I like the idea, but not from Legendary. It'd have to be done by Toho, because Toho can, and usually does, create outlandish Godzilla movies. That being said, I'd love to see the movie, just not yet though.
