Stephen Amell has come a long way as far as his acting, especially in scenes requiring happy or sad emotions, is concerned.
He was absolutely useless in such scenes until season 5, if I recall correctly.
All he could manage fairly better before was keeping a straight face or being ruthless in action sequences.
This last season was such a refreshing change, not only in terms of his performance but also the overall narrative which started to feel like a drag.
Will definitely have some good memories from this show.
