Harry Potter and the Deathly Hallows Part3

Rating: 4/10 (28 December 2019)

I'm a Japanese student so not good at writing English, but I wanted to share my confusion generated from this film.
In the opening, as the texts coming up,I was disappointed. How did Palpatine survived in the core of Death Star? He only lost a part of fingers.Other parts weren't damaged at all.If he could have controlled his body with force after he had died, were there any meanings to kill him? He would show up anywhere like Yoda. May the Palpatine with you,Rey...
I also didn't like the way of using force. How many Jedis could have been revived with "healing"? Did they just leave friends to their fate?
I don't want to dislike Star Wars any more, so stop remembering details.
