It's been a little over two hours since I started fedora-review and it seems I'm hitting these two bugs:
* dnf repoquery --resolve is extremely slow #1279538
*
fedora-review queries too many times for same thing #1275275

I'll try to stay up until it finishes and if that takes too long, I'll let it run all night and check up on it in the morning. If it fails, I'll go through the items on the checklist manually...
Really sorry for the delay.
