This review from Peter Travers of Rolling Stone explains why ‘The Last Jedi’ is everything you can hope for in a Star Wars flick. Here are some of the type of arguments that he made:
1) The Last Jedi provides all of the old nostalgia of older Star Wars movie (like lightsaber duels, space dogfights, fantastical creatures, etc.) while taking the series to the “next level”, with characters that are much more complex than being either good or evil.
2) Rian Johnson, the director, infuses the film’s characters and plot with twists you will never see coming, making the story both engaging and refreshing.
3) The acting in the film is incredibly well done, especially from Mark Hamill. Hamill, as Luke Skywalker, gives the best acting performance of his life. His performance is ultimately responsible for the film's greatness.
