Honestly, i don't think it will be a masterpiece or the better predator movie ever. But i do think that it can be a very entertaining movie, with good pacing and acting. If well executed, it can give us some memorable scenes.
Regarding the predator mythology, i think it can add some interesting stuff, and some other dispensable stuff too. It's what i expect, not the better predator movie ever, but heavy doses of fun, badass stuff, funny lines, some gore and great action sequences with good directing and editing. I think we can get that with Shane Black.
If we do, i'll be delighted. If not, i'll be fair and objective regarding what went wrong, and if the movie deserves to be atomized, i'll atomize the f**ker.
