Too much about Bo's love life?
I did enjoy the first few seasons of the show, but I really think they focussed too much on Bo and who she should be with. I felt like this became the main focal point within the show and the weekly mysteries really suffered. It wasn't enough that there was Dyson and Lauren, but then they had to add Tamsin into the mix because "everyone" falls in love with Bo. I hated the Teams that were created due to the relationships and I found it really made a lot of fans negative towards one another. It really reminded me of LOST with the Jack/Kate v's Kate/Sawyer. It just diminishes my enjoyment of the show when it is all about who is with who.
When I rewatch shows like The X-Files and Buffy, they had interesting stories that kept me wanting to see more. They also dealt with monster's of the week, but it was just written better and wasn't over shadowed by Triangle or square relationships.
