I’ve done some Cure Dolly forum battling in the past.
There are the occasional typo type errors in her videos that happen to any channel/book, however I’ve yet to see anyone point out a fundamental flaw in her content that didn’t end up being the person in question simply misunderstanding the content.
Granted, she can be a bit confusing at times. There were a few instances where I too had misunderstood her and thus learned something incorrectly, until someone else pointed out that she taught it wrong and I checked, only to realize that it was actually taught correctly just not clearly.
Often times if you watch the 3-5 videos before that given video, it’s much less likely you’ll misunderstand it. She sometimes leaves critical info out of an individual video because she’s already harped on it so much during those last few ones, and assumes you would definitely already know that bit, so why repeat it.
I found that when I first watched her videos, I thought I fully understood them. Then I watched them again from the start a few months later and it was like I unlocked a hidden level. It might of even happened again on a third watching, but regardless, I always watch her videos in chunks now, rather than isolation.
