It definitely is better.
And TFA is in my opinion better than ROTJ.
But it is inarguably, factually better than Ghostbusters 2. This is not an opinion.
I really should go in and finish my ROTJ edit I started years ago… I really think I was on to something. I was pretty much done with it but it was in SD and when I restarted it in HD I just never could muster the necessary enthusiasm. I blame my lifestyle.
