Would highly recommend:

• Flame and Citron for historical interest. Its about two guys who are part of Danish resistance movement fighters during Nazi occupation of Denmark.
• Another Round for their take on life, its about a group of friends trying to find the sweet spot of being drunk the right amount, its a bittersweet story which is just brilliant all around.

To skip if you really have to:

• The green butchers is also fun, comedic and morbid, you'll end up empathizing with the characters even though they are really weird! In a similar vein Flickering Lights is a light watch which is a sweet story about a bunch of friends who find new meaning in life together.
• Arctic, the door can be skipped if you really have to choose otherwise i'd watch them too!.
