This has probably been covered, but has there been any definitive info on how in the ever living hell they could see Hosnian Prime exploding from outside Maz's castle?
Even if it was in the same system, seeing what they saw the way they saw it could have been difficult in broad daylight. But that's at least remotely plausible even if sort of odd that this pirate stronghold would be next door to the capitol.
OR, even worse, is Hosnian Prime light years away in some other system, but J.J. made it visible in the sky for our heroes to see just because it looked cool, or as an incredibly weak plot device of some kind?
Loved the movie, but almost everything about the concept of Starkiller was easily the weakest part for me, with this particular nitpick detailed above being the weakest.
