I give season 1 & 2 10/10 Season three was so hard to watch I turned it off after three episodes and goggle the reviews to see if it turns back around, it doesn't.... how disappointing.
In Season 1, I was on my toes and creativity and structure of the directing was amazing... I am not a binge watcher but it was hard to not watch multiple shows in a row.
I was always on the edge of my seat. The romantic interactions were enough to keep you wanted to see the next step, but didn't take away from the plot
Season 2 started a little slow but the build up was worth the wait. And the last show I was so intertwined with. Finally Booth and Alex could have some time together away from the team and finish the connection we were all waiting for.
Season 3.... OMG Shelby! Will with the bad guys, and they ruined Alex's current relationship in the process. Nope they ruined it. This weird twists were drastic mistakes. Almost as bad as the ending in "Lost" but that was an episode, not a whole season. It made the whole series a mistake to start watching. Don't bother
