Yes it’s normal, but it’s not that much sauce. The sauce is on top, and the cheese and meat are below. What you’re seeing is only the top layer of sauce, hiding the deliciously gooey and savoury layers below.
Don’t watch the prequels first. It’ll spoil the original trilogy. Machete or release order would be good.
Once you’re done 1-6, watch the others at your own will. Solo, Rogue One, the sequels, any order (but watch the sequels in order).
If you really get into all of the above, check out the Clone Wars animated show (watch it in chronological order), then Rebels. I would recommend watching the live action shows after the animated stuff because they continue a lot of those stories, but you could do it either way.
In my opinion, the best way to watch ALL of it is to watch it in release order. Nothing gets spoiled, and everything gets built upon what we already know.
The mindset of “this kind of works for us, don’t change it, even if what you have is better” is at the root of most issues with America. Healthcare or Kraft Dinner, American Exceptionalism is damaging.
It’s $50 every 5 years. As someone who’s sat in border lines nearly 2 hours long, it was an easy buy. The eased up security in American airports is just a cherry on top.
