I always think that the best series have the highest investment (time) and the biggest payback - Severance is worth sticking with but you have to be prepared to invest your time - it's not a wham bam thank you mam type of series. If you need constant changes of pace then give this one a miss!!
The series i get the most out of are the ones that you randomly start thinking about hours or days later when parts of the plot come to mind as you unravel it in your subconscious
The only long series i invested highly in that was total crap was Better Call Saul. Just thought it meandered pointlessly and was relieved it was over as it bored me (controversial opinion i know)
@chesterbells yes totally know the scene you're referring to but it's nowhere near as bad as the scalp (off and back on) scene in American Primeval that i had to get my missus to tell me when it was safe to watch!
