1. No. I originally leaned yes but I think if it's not under Defenders, it'll be harder to find in such a large tagset than if it's under the individual fandoms. However, I don't have strong feelings either way.

2. If it does get grouped together, Marvel Defenders or Marvel Netflix sounds good to me. Shows to include: Daredevil, Jessica Jones, Iron Fist, Luke Cage, The Punisher, The Defenders.
