I always thought That early part 3 was great for what it was (Araki testing the waters with Stands and what they can do) but it really took off when Iggy fought Pet Shop. You really felt for Iggy during that fight too. All he wanted to do before he joined the Joestar group was **** biddies and eat coffee flavored chewing gum
. He went out like a real G though in the fight vs. Vanilla Ice.
The baseball episode was also very good.
The way Avdol went out was so sudden and brutal. No fanfare or great fight. just poof and he's gone.
And Joseph is my favorite Joestar. From all his antics in part 2, to all the shenanigans in part 3. He's the best.
Here's a bit of advice for part 4 if you haven't caught on yet. It's supposed to be a mix of Shounen, Slice of Life, and Murder/Mystery genres with stands. So, if there are episodes where they aren't fighting, and there will be, don't write it off as "falling off" as so many tend to do in here when a series does something they don't expect.
Part 4 has some fantastic episodes where they don't fight. Just you wait and see.
