Emily Deschanel really makes the TV series [em]Bones[/em] sizzle. She does a great job of making her character seem highly intelligent, despite her statuesque beauty. Supposedly, this is because the actress herself is quite intelligent and was cast with that purpose in mind.
The TV show sometimes stretches credibility to the breaking point, such as when it uses its magical holographic technology or makes wild inferences. Most recently, it played up the leprechaun angle in last week's storyline, requiring one coincidence after another. The show itself is still fun though, due largely to the interactions between the two leads.
