Well we already had Monster Trucks, but you're going to have other contenders. They spent 100 million production budget and at least another 100 million in marketing a Guy Ritchie King Arthur film. Perhaps I'm wrong but I don't sense any buzz for it.
Already called dibs on King Arthur for the same reason as 'monster movies', the market for these re-do's just isn't there. I suspect
over-familiarity plays a part there, but aside from Van Helsing I can also point at Beowulf as an example of 'that shit don't work no more'. Also, at the turn of the century, The 13th Warrior also bombed, despite being, as far as I remember, a pretty decent movie.
That is, it doesn't work as big budget action (schlock) movie.
Even midrange, like Victor Frankenstein (2015) when focused on action and not gore-horror, bombs horribly.
I'm sure Kwinston's data would paint a less subjective selection picture, but who can honestly say they would WANT to see another action movie attempt at any of these 'historical monster movie' myths? And while King Arthur is technically not part of that, I'm putting in the same 'myth' category.
Personally, I feel that we've seen, heard, consumed, and otherwise been exposed to that material so much (let's not forget all those fantasy games and novels) that there's nothing more to gain from it. Like, what would you even do with it nowadays that's new and interesting? I mean, I avoid fantasy games and novels like the literal plague at this point. Demons Souls / Dark Souls is the only exception because it does something different (at the time), as well as back on the movie end something like Valhalla Rising, which is more an art movie then a 'Viking' movie, but I really need something new from it in order to be even remotely interested.
And in that context, Van Helsing (2004) grew on me with time as the best that material had left in it as a 'big budget action schlock movie'. How you feel about that movie, or any other, is besides the point of whether it's profitable to make them. Transformers movies are profitable, despite being abominations of cinema. Myth movies played straight apparently are not anymore, even if the upcoming Bay-dump actually does use that. I do wonder if that's going to work against it in the BO, which will be interesting to see. If anything, that should demonstrate a negative relation if it actually exists on its own as a factor.
edit: also, the thing I actually bet on as 'biggest bomb' is a remake of the Six Million Dollar Man featuring Mark Wahlberg, which apparently is a thing that's supposed to come out at the end of this year, that nobody in the right mind asked for.
