Best defined as what it isn't:
The Bends part 2.
Which is a shame.
Some parts of it are OK, but OK computer isn't even on the same level as The Bends. This album signaled the end of Radiohead as a truely great band, and the start of their decent into random, irrelevent, pretentious, student pleasing rubbish.
Please, please, give yourselves a slap and write another classic.
