Saw the trailer. Everything was great, except one cliche - Rebels are cool good guys who fight like Rambos, and Imperial forces are blind idiots with crappy walkers which can be destroyed with several shots. Seriously, have you noticed the infamous 'stormtrooper effect' in that trailer? Especially walkers - they were sooo 'precise'. Ehh, could they stop depicting Imperial forces like comical operetta villains? Lore-wise, imperial stormtroopers made everyone sh*t their pants. They were literally feared because of their combat experience and mastery. But no. It's Disney. But, to be honest, Lucas is guilty, too. It was him who started that 'stormtroopers are blind dorks' trope.
Aside from that, the trailer was awesome.
