Better Call Saul has always had a direct road to Breaking Bad but nearly the whole show stood on its own. The last 4 episodes, especially this finale, all but abandons Better Call Saul and jumps between a few timelines during and after Breaking Bad. This makes the ending mostly unsatisfying and barely present.
HOWEVER, if you're a Breaking Bad fan you may still enjoy this. This is the reason for the high rating. It's basically Breaking Bad deleted scenes and conclusions for a few characters. This is basically an extended ending to Breaking Bad, not Better Call Saul. Love it or hate it, that's what this is.
A much better idea would have been to dedicate the last 4 episodes to finishing the Better Call Saul timeline. Then, these last 4 episodes could have been a post-show movie similar to El Camino. Unfortunately, we will be stuck with this.
