Hi monie
I think you only have to read a lot of the posts that have been posted on here over the last month or so to see that you are not alone in thinking this.
Last year I got hooked on BB from day one and, as you say, was addicted 24/7. I found this years really hard to get into and agree completely that there are no real characters and the people aren't that interesting.
I must admit that I am quite into it now, but nothing like last year. I'm following it, but in a much more detached way, watching and quite enjoying it but without being attached to any of the housemates. Last year I really cared who won - I so wanted Helen to win

- this year I really don't care, it's more of a case of who I don't like the least!!!!
