I didn’t watch this video but to me, the “where Picard went wrong” was clearly revealed in the first after show about it: one of the main writers was rock hard with excitement to tell us all about how he really wanted to prove he could do a dark star trek show, which to me, seems to miss the whole point of star trek. That guy is what went wrong with it
It’s not so wrong as to not be worth watching, but it does drive a need to be ready for it rather than a need to consume it, and so I have still not seen the whole show yet
