Well, actually I almost agree. I thought Heaven Sent was pretty boring while Peter was great in it. It is somewhat confusing but that's why I think it benefits from a rewatch, or at least reading a plot summary. But I didn't find it nearly as confusing as the explanation of "the hybrid" in He|| Bent. I still to this day don't know what the hybrid is, other than it has something to do with The Doctor, and he broke the rules and erased his memory, and blah, blah, blah. But, that being said, confusing plot wrap ups aside I actually like He|| Bent. Sure they kind of ruined Clara's exit, and the stuff with Ashildr felt a little pointless, but other than that I don't have the same gripes with it that others seem to.
