Biggest pros

The prologue is one of, if not the very best of the entire franchise.

I happen to like the Whitney subplot. It's something different for the series.

Bree's dance.

Chewy's death is one of the series' best.

Bree's sex scene is one of my favorites of any movie/show ever.

The remaining characters arguing over what to do when the lights go out and hearing Lawrence getting killed outside is one of my favorite sequences of the franchise. It was supposed to be even longer. I also think they made Bree seem even worse by the way they edited her reaction shots.
