Reviews of Luxury hotels are highly subjective as you don't know the authors point of reference. Are they comparing to the FS George V, The Tuscon Doubletree or the local Microtel?. For this reason I agree that reviews on TA are of limited value.
As a photographer I do place some value on the photographs posted on TA and similar sites. The professionally done images that are posted on the hotel websites are of course intended to create the best possible impression of the property. On the other hand a decent snapshot will often be a more realistic depiction of the subject.
