Disclaimer: I'm not a big enough fan to get wrapped up in the minutiae and put the magnifying glass on this.
BUT as a person who has seen all the ones from the 70s/80s (at least once) and none of the ones from the 90s, I found this thoroughly enjoyable and incredibly true to the flavor of the originals. I thought it did a great job of incorporating the core elements Lucas brought to the big screen (early on) and updating it, without a heavy hand, with modern cinematic techniques.
Definitely worth seeing in the theater - it will give you feels.
This is the one that taught me at a fairly early age that a film can be, and wonderfully often is, so much more than mindless entertainment.
I've heard it described as a love letter to cinema and I like to think of it that way too, so perhaps it's no surprise that it set into motion my own lifelong love affair with the movies.
That alone, is reason enough to give it ALL the stars.
