Just compare the Rebel attack on the Death Star in the original film to TFA. In Star Wars it very much came across as a real military battle, albeit on a small scale. This film had nothing like that, it was just yippee pew-pew we did it. No tension. Nothing.
100% agree. It was action schlock. No setup, no tension. Not much care or thought was put into it.
ROTJ has a repeat of the Death Star, which is a negative, but at least the battle is pretty exciting and tension-filled.
