Who are your top 3 favorite characters from part 4?
#1 - Kira
#2 - Rohan
#3 - Hayato
What are your top 3 favorite stands from part 4?
#1 - Killer Queen
#2 - Pearl Jam
#3 - Highway Star
Heaven's Door and Crazy Diamond
Ryan would've been #2 and #3 respectively if Araki wasn't inconsistent with their rules such as Crazy Diamond not being able to restore something perfectly or Heaven's Door needing a manga page to work. I guess if you were to speculate you could say it was due to their developmental potential allowing them to overcome this limitation, but it seems a bit of a stretch when both have this flaw lost after their introduction (not to mention CD has a mediocre C for potential).
Who are your 3 least favorite characters from part 4?
#1 - Oyanagi Ken (the Janken kid. Seriously, what was his purpose in the story?)
#2 - Kobayashi Tamami (so inconsistent his height can't even stay the same after a beating from Koichi

)
#3 - Katagiri Anjuro (way too over the top and edgy)
What are your 3 least favorite stands from part 4?
#1 - Love Deluxe (at that point in JoJo, having just super strong hair is pretty plain)
#2 - Boy II Man (way too situational)
#3 - Ratt (a rat shooting corrosive darts is cool, but without the user than Stand is meh)
What is your opinion on Rohan and Heaven's door?
Rohan was a decently developed character. His introduction arc did a good job at presenting his eccentricity and passion for his work. Though it was repetitive at this point to see yet another minor antagonist be instantly forgiven by the main cast, he's at least the only one other than Okuyasu to play a major role in the plot. Once Reimi gets introduced and we learn about how she relates to Rohan, his goal to avenge her becomes quite compelling with him seeming to be the only character other than Jotaro to put much of a proactive effort into tracking down Kira when he's in hiding. Even when he's forced away from the search for Kira on occasion such as during the I Am an Alien and Highway Star Arcs, we get a great look into his character such as his contempt for Josuke, his kind nature beneath his visage and his determination to always come out on top.
Even after DiU through supplementary works in the Kishibe Rohan wa Ugokanai collection, whilst we don't get a real deeper introspection into his character, we do see his ability to adapt to many alien situations such as being forced to abide by the etiquette laws of the mansion, showing how he's mature and calculating enough to try and find a way to handle most situations.
Rating him as I would other characters, a 7/10
As for Heaven's Door, it is a very interesting stand due to how well it links to it's user's personality and the affect it can cause in battle, though it is a bit too overpowered for the story's own good when it acts as too convenient a source of information, especially when it's one of the faster Stands as well. At the very least, it should've had it's speed nerfed to around D or C tier.
Definitely up there on a list of Stands I'd want, but as far as how it affects the overall plot it was far from balanced.
Which is your favorite part 4 opening theme?
Great Days. No question about that.
