I love this double compilation album. I think the negative reviews miss the point. These are highlights from Radiohead's albums blended together and specially sequenced in a thought-out fashion that offer an alternative approach to their vast library of music compared to a rigid album per album listening, which I agree is also beneficial.
In addition, you will not find "Talk Show Host", an amazing song featured in the film Romeo + Juliet, on any of their albums so that is a worthwhile inclusion. Granted this album is not for purists, but for more flexible people who do not have fixed ideas about what Radiohead is about and how their music "should" be listened to, I think this is a darn fine double compilation album. I also agree with the choices made and I think they are representative of that special Radiohead energy that took me years to fully grasp.
The Bends and OK Computer are the most featured albums with a total of seven tracks each (on the double album version), then comes Kid A with four, Hail to the Thief with three, Amnesiac with three and Pablo Honey with three.
Of course, Radiohead have produced great works since those days, most notably In Rainbows but also King of Limbs (which I'm very fond of) and, at the very least, this compilation album shows the extent of their genius as an alternative Rock/Electro band.
