I seem to disagree with both sides here. in my view r1 is a better made film out the gate. But I don’t think Rots is “nothing but rot” either. It’s bloated and has problems, but in my opinion it can be “saved” in editing. And that doesn’t mean it can get anywhere close to the level of ANH or ESB, but good enough to enjoy watching.
Even in edit form R1 is probably a better film but I just find rots more enjoyable. Unedited though I would rather watch R1.
