Sam in Eastenders!!

Sorry but what is that all about, they change a character totally...not only in personality but the actor is different.

So Kim Metcalf who played Sam when she helped conceal the body of Den and then fled to Brazil to get away from a police sentance. Now Sam in those days was pretty confident but fairly serious and business like, if not a little bit dappy! So what has happened, even if we take out the fact that they have now replaced her with Daniella Westbrooke, she would never have behaved like she did in that episode last night...i just dont get it to be honest!! It was like watching your Dad dancing at a wedding...embarressing to say the least!!  Does anybody know why Kim left or was it they wanted to replace her??? i don't understand why i liked Sam before and i dont think she was "unpopular??" who knows...what i do know is Eastenders must be struggling. They Have Bianca and Ricky back fairly recently and now Sam...maybe they are missing the fact that it used to be more popular than it is therefore they are dragging them all back to try and coax more of the older crowd to watch it maybe....?! Don't get me wrong i like Ricky and Bianca and even Sam in fact i used to watch it alot more when they were in it...but its just not the same. You can't reinact something that happened many years ago...not really especially as these characters seem like they are a little bit stuck in the 90's!!!

Can anybody tell me why there is no happy endings in Eastenders, i am no expert or anything but what is that about...if people get married they have to have some tradegy like losing a baby or even being killed by the local Mafia type bloke! Its getting more and more predictible aswell, Corronation street is the same you just know whats coming...not only because you read about it in the paper or hear it from friends but its just so obvious!!
