I have no problem with him taking inspiration from other films like Lucas did (with the exception of Dam Busters which he completely stole from) but it’s how he implements the inspiration that is cause for concern. Also I’m curious, what makes you think Episode IX couldn’t be even better than VIII?
EDIT:
Also most pro TFA people know it rehashed things from the OT but there are a small few who think it’s completely original. Then there are some of the anti TFA lot who think it’s a step away from being a full on remake. I don’t understand either stance.
