We need a season 7 of Teen Wolf because it was an amazing series that deserves to be renewed and we know that Jeff Davies has storylines for a lot of other characters to come back for the final episode but didn't have chance, so renewing the show would give him that chance and give proper closure for the show. The end seems so vague, and we need to know what happens to Scott and Stiles and all the others fighting the war, and what happens after.

And in season 7 the show could focus more on the colleges that they go to and their school life rather than the supernatural and maybe have a bit of supernatural drama throughout it. This would give chance for the writers to really give stydia the ending they (and we) deserve and also maybe focus more on Scalia and of course make sure thiam actually happens because they deserved to be together.
