To read or not to read - that was the question after I read a lot of reviews, and then the introduction in which it was clearly stated that Alan didn't want this thing to happen. He didn't forbid it, but declined co-operation and stated he didn't want to look back (yet). But the author decided to go for it, anyway.
The only reason I give it 4 stars and not less, is because of Alan. It's as simple as that.
Very often I was put off by the writing style, structure, choice of words, choice of focus. There are many repetitions that could have been avoided by better structuring the text, for example, and which weren't necessary. All the time, it feels, the author was focusing on Alan's sexually attractive aura, how everyone is just crazy about him etc., and sexualised him heavily - to put it in a simple way. Felt rather disrespectful. Even if it's true and many feel this way about him - it's nothing I want or need to read about on every other page. Nothing would have been lost, but a lot gained, if the author would stick to a rather neutral description, I think.
What was nice to read are Alan's own views cited, and everything his friends and colleagues had to say about him. I've always admired and respected him deeply, since I've discovered him, and I always had the impression of him being a very good and lovely person. So it was nice to see that he truly was, on so many levels.
