The video contains more content, but in short, I thought the good aspects were the characters (especially Deadshot, Harley and Joker, El Diablo, and Amanda Waller), the opening introductions, and the character-based denouement. Elsehwere, I have also started to unpack some of the movie's themes, and there is more there than I initially thought.
For me, the bad was that there were a few too many music cues with rock songs, the middle section dabbled in generic action territory, and I thought a couple emotional pay-offs were set up but not set up thoroughly enough. The ugly was probably just the mystical Enchantress in Midway City (not the smoky witch version... I liked those parts), but luckily Enchantress was actually just the tool of the real villain, Amanda Waller.
