Some pointless issues:
Why after the opening crawl, and panning down to Jakku in the background, WHY do the troop transports fly towards the CAMERA, i.e. IN THE OPPOSITE DIRECTION
Also when Threepio realises hes cockblocking, BB-8 goes with him not INTO the rescue ship, but into the wreckage of Maz’s Castle? but then Chewie has some intelligence and actually goes into the ship
