I quite liked his introduction! Be aware, however, that he dramatically overstates some things. For example, he claims that the many-worlds interpretation is obviously correct. This is basically wrong: it may be correct, but it certainly isn't obviously correct, and many scientists whose entire research is dedicated to quantum mechanics would disagree that many-worlds is correct at all.

There is a long list of alternative explanations[0], with very little evidence to lend support to or contradict any of them (at least, any of the ones that are still around. Some have fallen by the wayside).
