I realise that currently I don't so much review on this blog but more talk generally about my impressions of what I have read or seen. This is because I live in fear of the dreaded spoiler.
There is nothing worse than reading a review and all of a sudden a major plot twist is revealed. There has been a lot written about this recently as the current chief writer for Doctor Who was very disappointed and angry when details of the new series were released on the web by a fan after a special screening.
If you chose to read the last page of the book to find out what happens then that is a personal choice, to have this read to you is a problem. However where do you draw the line? Take for instance my recent trip to see Much Ado About Nothing. The play itself was written over 400 years ago so isn't new but I for one had never read or seen it before the weekend just gone...is writing about the plot for this a spoiler?
Also there is the danger that in writing a review to remain spoiler free you just end up writing a plot summary.
I've got a book on review writing on order at the library to see if I can pick up any tips but I think that a personal impression is a valid form of review, it might not be erudite or intellectual but it is honest and spoiler free!
