BvS should sweep all six categories in which it is nominated.
If their was any Justice in the world.

To make sure they win, go spend money on those votes.
They counting on the likes of you to give them money, so you can gloat oh wait, you won't be able to, not here at least, neither on cbm, oh.

It is 8 nominations but even as someone who dislikes the movie I do find some of these nominations a bit strange. I think that it has a chance of picking up maybe three. Luckily some truly dreadful movies came out last year the other DCEU movie was actually worse than BvS so SS may well take away the chance of BvS picking up too many.
To make a great film you need three things - the script, the script and the script -Alfred Hitchcock

8 wow.
I don't think it deserved that many even though it wasn't a good film

I honestly don't like the Razzie Awards, and I don't find them reliable critical results. One of the problems with the Razzies is that they appear to rarely nominate only a few legit nominees per movie.
I didn't like Batman V Superman, but I don't think it deserved a nom for worst actor, picture, and supporting actor. Especially since Ben Affleck was probably the best part of the movie, Cavill wasn't bad, just boring, and I dare say Jesse Eisenburg was a good actor (of a crappy character).

8 nominations in 7 categories (Affleck and Cavill both got nominated for Worst Actor)

If you can't defend a movie without bashing another, you will be put on ignore. No exceptions.
