I really don't think that Avatar made $2,800,000,000 just from it being in 3D.
I don't know why but some people ( not having a go at anyone on here ) can't seem to accept that people actually enjoyed the movie.
They always put it down to " The 3D was a gimmick " - despite it being one of the best 3D movies - not only at the time but also since.
Or it only made that much because it was re-released.
Star Trek 2009 was in the cinema for six whole months and made a whopping $385m so that's not it either.
And as for the basic plot. I actually liked it BECAUSE of the basic plot.
tl;dr - some people liked the movie despite all the "gimmicks"...
NOW - STAR WARS.
I might actually get the Theatrical Trilogy on Blu Ray and i'm interested in Force Awakens and will go and see it. But i'm more excited for Star Trek Beyond, obviously
