Tbf even though it wasn't needed they showed a new camera angle to check the Talanoa try from the side high up.
For the Ellis try it was very tricky TBF. Initially it's not touching the line but it does eventually. It's not so much a double movement of the arm but a wriggle of the wrist to move the ball forward. As a neutral I wouldn't complain either way it whatever the decision. Under the system of on field ref decision then you couldn't really overrule it. Even under the old system it's an awkward decision to make.
