Geelong coach Chris Scott says the AFL's score review system is a raging success despite a flashpoint in his side's win over Port Adelaide.

For Geelong coach Chris Scott, all's well that ends well.

But that doesn't completely soothe some unease at an AFL score review flashpoint in his side's 12-point win over Port Adelaide.

In a tense final term at Adelaide Oval, the Cats were five points up when their Brownlow medallist Patrick Dangerfield and Port's Aliir Aliir chased a ball dribbling towards Geelong's goal-line.

Aliir dived head-first and Dangerfield lunged feet-first, appearing to get his boot-studs to the ball just before it crossed the goal-line.

But the goal umpire signalled a point and despite Dangerfield's appeals, play continued without a video check from the AFL's Arc review system.

"If we had of lost by a goal or a point, I would probably be a little bit more expansive," Scott said.

"I am an advocate for the Arc and everything the AFL is doing there but ... my view is, if there is any doubt you should review it."

But he said the score review system wasn't cut-and-dried.

"I don't like the hold-up in the game," Scott said.

"Especially in a close game where if they review it ... turns out it was a point, you have denied Port the chance to move the ball quick out.

"So I don't think it's as simple as 'you should have reviewed'.

"I must admit, I had a quick look and I thought it was a goal so it was close enough to have a bit of a look at.

"But all is well that ends well, I guess."

Scott described the score review system as an overall "raging success" - with one caveat.

"This idea that they review kicks from 50 metres away to see if it's touched - that is not a score review, that is in-play decision that should be left to the field umpire," he said.

And he believed the AFL community should "put up with some human error to keep our game really dynamic".
