Wow people really don't like this movie.
By people I mean the "hardcore fans" and not most other people such as the movie goers who these films are made for, yes fans your not that special and important as you think you are.
This movie was perfectly fine and I enjoyed it as well as the fact it did not go the way I expected it to, it does have a few problems but things like Luke's fate is not one of them, Luke went out in a beautiful way and that's ignoring how the film sets up his return in the next one having become more powerful by ascending into the force and becoming one with it.
Snoke's death was damn brilliant, they should have explained more about him yes but the death itself was clever Snoke was made way to powerful for him to have a reasonable way to be killed in battle or something so the only way to kill him decently was to have him be outwitted like all Sith are.
Plus I really did not want Snoke to be a complete Emperor rip off.
