I think that Poppy is a great actress and makes Without A Trace all the more better. She is convincing in her role as an FBI agent, but she is also believable as a caring person when she lets her guard down.
As Without A Trace continues on TV Poppy will deffinately become a more talked about actress. If there were more Poppy Montgomerys on TV, there would deffinately be much better TV to watch. Though she is often overlooked as part of the great cast of Without A Trace I think that people do realize the talent this actress holds when she has her chance to shine.
