I'd call Games art because while a movie the art of the director, games are one that let you finish the experience. Movies play whether or not you touch anything, but games will sit at the same screen until you take up controls. Death is like a missed stroke, or a botched line. But you have the chance to get it down before you continue on.
As stated, games and movies are totally different types of entertainment. Movies are made for us to relax and watch, characters and events happening for us to enjoy the viewing pleasure. But games are made for us to BE the characters, to cause the events, and to work through a problem the way we want to
Now not all games are like this. What I just said is mostly sandbox or more open games, like Bioshock, SoTC, even GTA games are like this. However, based on yahtzee's review of Siren Blood Curse, some games are more like a movie in their art, where you can only do it a single way. Pointing from his review, it lets you do one and one thing only to get the plot, but it's still made and caused by your actions, and lets you appreciate and feel for the characters when you control their fate. Even if just one fate.
I can understand RE's opinion, because again as stated, he hasn't played it, and only seen videos of it. Watching someone play a game and experiencing it yourself is different. While watching someone face Meta-Ridley in Metroid Prime is nice to watch, you have to play to really feel what it's like. I remember playing it once, and so into the game that I was moving the sliding chair I was in while dodging on the game. A good movie can do this possibly, but not the extent that games do it.
His opinion is right from the basis of how he's experienced games, but without ever having a controller in his hands, he won't ever be able to have one that's right in every aspect of a critic
