Shows like "FROM" similar genera, vibes.. as good and addicting.

Watched Lost years ago. Its really important that I find a really great TV show similar to FROMs vibes. Reason being, my partner and I got SO lost in it for a week and BINGED the 3 seasons in about 5 days. It was SO nice. She is not one for a series really. She is a movie gal. I am a series guy. It was really nice laying around with her for hours trying to guess and solve the mystery's and coming up with our own conspiracies. We both really enjoyed it a lot and I would love to do it with her again! Please help me out you wonderful people of reddit! <3
