Overall, I think it's fair to say that both season three and the finale of Arrow were a disappointment. The show introduced a lot of great plot points but failed to ever really capitalise on the majority of them, while the ending with Malcolm taking over the League of Assassins felt like the very definition of a cop out to avoid changing the status quo next season. Oh, and don't even get me started on that Olicity nonsense! Regardless, the final episode did feature a pretty amazing fight sequence between Oliver Queen and Ra's al Ghul, and you can watch it in its entirety below.
