The OP was very well done and I'm glad they stuck to the style of the PV. The episode was handled well, adding in more content and did Giorno's backstory justice. Bravo to the staff.
Here's a nice tidbit about part 5's production. I noticed the Cacani logo on the ED.
It's fairly new too, here's promo video I found
Speaking of that ED, people as usual will complain about an OP/ED song then end up loving it. I love this ED song, it was so unpredictable and somehow fits with part 5 in a bizarre way. What my main criticism comes in is the slideshow ED, it's a big downgrade from DiU's ED. It's a slideshow with some references to future events. It's not awful by any means but it's a downgrade from part 4's ED. They really need to beef up this ED but not sure if it will get drastic changes like more animation. Other than that, I did like the flair of the ED, fitting for the song, just would've liked it not to be a slide show. Overall, a pretty good ED that will get better over time.
