Beckham's book is what it is.
But let's look at some positives. It brings photography to the forefront of peoples minds and gets younger people involved. Which is good and some of those will be from a different walk of life to whom usually gets involved.
It shows that you can get a book published with a a bit of money

Not everyone can take a good photo.
Ok now let's also think that we have all taken better photos than Beckham which we all have I hope. But that doesn't mean that they are worth more. His photos maybe super personal to him (his degree will help his skill). Secondly when you look at "art" it doesn't need to be good it just needs to be sold. The most expensive photograph in the world is hardly amazing. I digress. Fair play to him I say stick it out there and think f*** it I'm loaded anyways. If he came here first and asked for help he'd have had his head chewed off photos lambasted and he wouldn't have done it. There is something wonderful with the teenage mind they know it all and are fearless.
