No Tyrion Lannister
One of the most challenging tasks that the new series faces is the loss of beloved characters. The likes of Tyrion and Arya brought a magnetism to Game of Thrones that will be difficult to replace. Furthermore, fans may negatively compare new characters to the ones they miss.

Peter Dinklage made Tyrion into one of the most iconic TV characters ever. He combined bawdy wit with moments of powerful poignancy on his way to multiple Emmy wins. The new cast has a lot to live up to with Dinklage’s small shadow hanging over them (via Variety).
