I don’t quite know what an “Exclusive Official Trailer” is though I have to admit that I really want to see Jiu Jitsu because – while it doesn’t look particularly good – it does look damn interesting.
It’s very much Predator (1987), combined with Mortal Kombat (1995) with a smidge of (the extremely underrated) Without Warning (1980).
In other words, it’s likely in terms of entertainment value to hit way above it’s weight class.
And I can’t speak for anybody else but I watch a lot of movies, and actually holding my interest for any length of time is not the easiest thing so when I find something that looks like it might do the job, then I’m there.
