The trailer for the Arrow mid-season finale is promising great things for next week’s episode. The mid-season finale looks tense, dark and very moody. It seems the story is going deep into the League Of Shadows side of the DC Universe which is very exciting.

We are finally getting a face off between Oliver and Ra’s al Ghul. As well as some kind of altercation between Oliver and Merlyn in which Oliver loses control and is seen trying to choke Merlyn to death, this should be a particularly impactful scene.

The episode looks truly epic, it appears to have the scale of a feature film with shots of Oliver scaling cliff faces and taking on ninjas in ancient halls. I really look forward to this episode, as should you after watching the extended promo above.
