Yes it is.
Isolation was an awesome game possibly done in sales wise by terrible reviews that left me shaking my head. The game isn't perfect, but I'm really not sure what some reviewers wanted out of a game based on Alien that Isolation didn't deliver. Apparently a tense and atmospheric horror game based on a tense and atmospheric movie wasn't what they wanted.
Unsurprisingly, IGN rated the rather bland and disappointing Aliens vs Predator higher.
I think the treatment of Isolation is a great example of why I have problems with review scores most of the time. Some games are penalised far more harshly than others for their flaws, and I suspect that it's games that try to be a bit different rather than nakedly mass market that are more likely to suffer. It's not a new thing either; I recently ran into an '90s review of Vampire Savior, a fighting game classic, that rated it 38% probably because the reviewer didn't know how to play it.
