You are reviewing a 6 year old game, at the time it was a very grapically advanced RPG.
The quake engine had never looked so good, there were actually colors other than gray, brown and green
The cutscences were considered very good they used a technique to strech and blend the textures which made the charaters seem more rounded which if I am not mistaken had not ever been done in a video game before.
I humbly suggest you reevaluate your score, as an example look at the Baldurs Gate review it has a 9 and there is no comparsion as Redemption looks much better.
If you did not play games 6 years ago then mabye try comparing Redemption to other 6 year old game you will find it was in the 85% to 90% range compared to other titles visually, 7 is extremely to low.
