The two villains are Hela and Enchantress but one of them will be the more sinister one and the other turns good near the the final climax of the film after she realizes the harm she has done. Amora is a femme fetal who do anything to get Thor's love and be his lover forever but she has good in her heart still cause she just wants to be loved so she is just an obsessed who is all about herself. On the other hand hela is not cause she is the embodiment of death and eternal damnation that collects worthy souls which makes a more powerful threat. Amora finds out hela's true intentions  after causing trouble just to be by Thor's side so she turns the tables around which is to save Thor's soul captured  from hela after Thor's  defeat. The enchantress is a very powerful sorceress so she is willing to battle hela's minions to get him then she performs a powerful spell to bring him back to the land of the living then they both agree to battle hela to get her. After her defeat Thor appreciates amora  a lot more but is married or in love with someone else like Sif for example. Amora finally  comes to terms but Thor offers her to be by his side as an ally along side Asgard to keep the nine realms protected. 

I think you need to see the first one before you start pitching sequel ideas.

I was thinking the same. It's easy to see that Loki is ending up in Hell looking for Hela help.

They announced a sequel when or before the first one even hit the theaters!

Personally, I hope the sequel is based off of Simonson's run  Imagine Beta Ray Bill with asgardians on Earth fighting countless swarms of demons and Thor and Odin (and possibly Loki like in the comic although that may be left out) in Asgard fighting Surtur on the big screen, how awesome that would be!
