It is amazing, I agree it has a bit of a sluggish start, but the final act is superb. That final scene, wow, that was what everyone wanted to see for decades. Saw it again today, still awesome. 
It won't beat A New Hope and The Empire Strikes Back for me though. Not sure where it falls after that, somewhere beside Return of the Jedi, The Force Awakens and Revenge of the Sith. Probably above Revenge of the Sith, so I'd say it's 3rd-5th. It's definitely better than The Phantom Menace and Attack of the Clones.
I realize mentioning "3rd-5th" makes it sound worse than it is, I am really surprised by it, easily exceeded my expectations. If Disney makes more spin-offs like this one, I'm definitely on board.
