Heimdall can literally see the whole universe in the Marvel Cinematic Universe. Then why didn't the Asgardians use him to find the location of the Infinity stones and keep them in safety in Odin's Vault? So no evil (like Thanos) can acquire them and use them to wipe half universe. Or they could use them for their welfare.
Why didn't the Asgardians aquire the Infinity stones using Heimdall?

Is B Movie a genre of it's own? Are there requirements that get a movie thrown into that category or do the producers specifically set out to make it a B movie?  Netflex will list B horror as one of the genres and I know there is a cult following of B movies.

In Game of Thrones there is a scene in which Yara tries to free Theon from the Dreadfort. During this scene we see Myranda and Ramsay in bed together. Myranda places her hands around Ramsays neck and holds them there for a long time. It then cuts away from them until Ramsay arrives in the kennels, covered in blood. Myranda is never seen again. This may sound like an obvious question but I'm just wondering if it's ever confirmed that Myranda tried to kill Ramsay. I googled it but couldn't find anything explicit.

Did Myranda try to kill Ramsay?
