Loved seasons 1 and 2 for their plot line. The characters are fun and dysfunctional. Enjoy most of the characters, lovable softy Luther, motherly Allison, crazy Klaus, hero complex Diego, even Ben as a ghost. Not liking the Vanya character's "growth", especially in season 3. Not my thing. I miss her music from season 1.
Shows the possibilities of why mankind should never muck with time.
