It has been some months since you guys got me into Jojo, and I just reached part 3. I was thinking of checking out the OVAs, how do they fare in comparison to the manga?
Also, thanks for getting me into this, it's fabulously awesome.
Not nearly as FABULOUS.
Watch the OVA's before you read the part 3 manga. The anime series is pretty good standalone, but a lot is missing from the manga. Most scenes with Dio are great in the anime.
Not as good as the manga as you'd guess, but definitely worth checking out.
