What's the point of The Observer?

It's been a habit for so long that I rarely question it .... but do I really get £1.90-worth of read from The Observer?
The Sunday Times isn't an option (I wouldn't believe half the things I read) and The Independent on Sunday just doesn't have the meat.
I think this book may have given me the last bit of evidence I need to convince me that I can survive Sundays without half a forest littering my living room floor.
