Both dramas gave apocalyptic vibe however in Dark Hole there are zombies/monsters that attack people who have to fight to survive.

Someone recommended Kingdom and season 2 is must watch too. Both series are about people fighting to survive in the world full of creatures that want to kill them.

In DAS there are evil aliens and in Hellbound some monsters from hell and people struggling to fight them.
