I'm kinda cautiously hopeful about this one. I like the idea of an alien arrival where no one, maybe not even the aliens, knows what's going on, and everyone has to figure each other out.
The language barrier thing could be very intriguing. I remember in "Contact" that the premise was the aliens could communicate with us through math, but that assumes an alien race views math the same way we do. "Contact" made a big deal about prime numbers, for example, but it never really asked if or why an alien race would care about prime numbers.
The thing that might make me steer clear of this movie is if it gets into some kind of political agenda.
