A few samples:
IGN, 9.7:
The true definition of a classic, the gameplay and story of Shadow of the Colossus are every bit as great and emotional today as they were in 2005. This outstanding remaster skillfully enhances those qualities with improved controls, performance, and sheer graphical beauty. It remains one of the best PlayStation games ever made, and it's wonderful that Sony has brought it back to the fore so a new generation of gamers can experience it without having to look past its aged facade.
Metro Game Central, 9:
A stunning recreation of one of gaming's most enduring classics, and what remains a towering example of the art of interactive entertainment.
Push Square, 10:
One of the greatest games ever made resurrected in one of the greatest remakes of all time. Shadow of the Colossus remains faithful to the 2006 original, but its presentation is on par with the very best that the PS4 has to offer. A masterpiece.
Destructoid, 10:
Not to diminish the accomplishments of this remake, but it's all possible because Team Ico's Shadow of the Colossus is so impossibly perfect. It's epic and majestic and emotional and imaginative and breathtaking. There are so many superlative adjective you could attach. Shadow of the Colossus' reputation is as great as some of its tallest colossi. This remake might just help some people see that a little more clearly.
GI, 9:
Shadow of the Colossus is a masterpiece, and developer Bluepoint has done a fantastic job bringing it to a new generation.
