I'll make this short. Personally, this is my favorite season so far (comparing to the first and third). It balanced between Seven's past and his present with the introduction of other characters. The opening may seem not that interesting, but it makes us wonder "is this some kind of a foreshadowing?". Absolutely love the color pallete and animation. This season really pushed Seven to "reunite" with his past self. Not giving him any option but to protect the island by tidying up the mess he made 2 years ago. Scissor Seven is painfully underrated, I truly hope it gets more attention as the fourth season airs.
