I'm not going to spoil anything but:
I really love this show, it's one of my all-time favorites. I love all the theories fans come up with and I love the characters. The casting is on point, the acting is so convincing and the plot in and of it self is brilliant.
I'm not going to lie it does bother me though that this show is very weird. If you look at any show, like The Vampire Diaries, they aren't half as crazy as Riverdale. This is because TVD starts of supernatural and sticks to that through the whole show, whereas RVDL on the other hand does not specify if it is supernatural and taps into that element then tramples all over it and says no to it. The writers (God bless their souls) can't really seem to choose if this is a supernatural show or not which just messed everything up.
But other than that it really is a brilliant show. I would 10000% recommend it.
