Yes there have been shows like this before and yes there will be shows like this in the future but what really makes a show are the plot lines and the characters, how they are written, how the actors play them and how well they mesh together.
I haven't liked a show this much in a long time, I have watched it from the very first episode and I will watch it until the (tuytuy - touch wood) very end. It's funny and honest and played extremely well by the actors. It has heart wrenching story lines as well as silly, stupid ones which I think a show needs. Yes it took a while to get the main characters together but thats what it needed. They did this at the right time. Too early and the show bombs, too late and fans lose interest.
The very loyal fans of the show have waited 6 years for Booth and Brennan to get together and in the end we didn't need this big fancy show of 'we are together llok at us shouting from the rooftops' as it isn't there style.
Brilliant Show - carry on!
