I liked the teaser! Of course I want to see more of the predator, also teaser did feel generic, but it's okay. And mask sometimes looks cool, and sometimes funny, so I am not sure about that. But I do feel good seing predator being bad ass, hope movie going to have a lot of this scenes (It's why I loved Predator 2, they showed him a lot, and he was bad ass!!!). So I would say I am still have high hopes for the movie
PS. I didn't read the script, but I do think boy was not controling the ship. I may be wrong. Also I don't think they showed upgrade in this trailer, I think it was captured one in the trailer.
