Ok, I've watched a couple random clips & the theme song (I really wish they'd go back to doing original songs for each season, but I think that's just me being "spoiled") The question remains, though, is this one actually worth watching?
I can already see signs of better acting & slightly better writing, though that may generally just be coming from the improvement of a varied cast.
I would consider A) the acting, writing & choreography actually making the situation seem perilous &/ or taxing. B) Things actually being difficult to achieve. C) more interesting characters, which I've already seen is a yes.
