I get the cynical take on post-Disney Star Wars, and you're right that capitalism is the driving force and films aren't made the same way they were. As long as TFA is on the same level as or better than ROTJ, I'll be happy.

Preserving the original Star Wars (Trilogy) is on a whole different level of importance, but I'm still looking forward to having a bunch of new Star Wars content to parse and enjoy. If it's not all that great, it won't hurt anything to have it out there. But I'll bet it'll be a net positive, as far as enjoying myself. I'm not a serious film guy or anything, so I'm just looking for an interesting story to follow.
