So the question is if you are not familiar with the Eternals and are going to see the film should you read this or read Gillen's issues. The unfortunate answer is...you should probably read both lol. This contains elements that Gillen has not touched upon very much like the Deviants or the Uni-Mind, though of course I have no way of knowing if those even factor into the film. This issue in turn though has no appearances by key characters like Sersi or Kingo who feature in the Gillen series. Therefore reading both is going to give you the fullest understanding of all elements surrounding Eternals.
In terms of just quality, Gillen blows this out of the water. But I will say I have a nostalgic affection for Macchio's old-school style, such as when Ikaris says "I can dodge their sluggish attacks all day and strike back with power only an Eternal can muster!" out loud with nobody else around. Classic. I also was amused by Ghaur having a minion dump acid on their own hand just to apparently prove to Ghaur's own staff that he is a real badass. Also classic. Artist Bachs keeps the art pretty traditional too to fit with the writing. Definitely an optional issue but I enjoyed it.
