The OUT is canon to me for sure, though I do have my reservations about ROTJ. I feel it could have been a lot better, it doesn’t feel like a proper followup to ESB. Not to mention I hate ewoks.
While I accept the overall plot arc of the prequels as events that happened in the SW universe, I regard the films themselves to be horrible depictions. I outright reject many elements in it, such as the presence of R2 and 3PO, midichlorians, and Yoda using a lightsaber.
I thought TFA was an average movie that did a great job at doing what it set out to do (a return to form, reinvigorating the franchise, introduction to new characters, etc.). While I liked it, I’m not sure if I consider it canon yet. Snoke seems extremely stupid and unfitting. I have high hopes for TLJ, if that movie ends up surpassing TFA, I’ll probably accept the ST as canon.
Also, hi, I’m new.
