I don't think you would want to see online leaks anyway; the leaks are usually filled with low quality, both picture and sound. Extreme food prices aside, you could always try a matanée showing which is cheaper. I say it's worth the wait. Lotsa people are saying it's far better than the prequels.
It's essentially a remixed A New Hope but with plot points that don't make sense and two new main characters that I didn't care for at all. And Kylo Ren was a pretty big letdown. It set up well for the sequels, though.
Wait a week or so and go see it in the theaters. The last time a good star wars movie was on the big screen was in 1983. Don't ruin your experience by watching shitty cam rip. The big spoiler doesn't ruin the movie, in fact it makes it slightly better.
