Is Matthew Perry getting worse as an actor?

[TMC]

He seems to have no variation in his facial expressions, and his line deliveries are all a sort of exasperated shouting, regardless of what emotion he's supposed to be conveying. Yeah, the writing isn't that great, and all of the characters are one-dimensional, but Perry really isn't capturing Oscar. Not that I want him to try to impersonate Walter Matthau or Jack Klugman, but they embodied a certain hangdog quality that just isn't there in Perry, and it's the essence of the character.

From what I understand, the role of Chandler on Friends was basically written to fit Perry's strengths. This version of Odd Couple isn't written for anyone. He arguably gave great performances on The West Wing and Studio 60 on the Sunset Strip that were dramatic roles completely different from his role on Friends. So I have to feel his current problem maybe he's being asked to deliver poorly written lines. Then again, Perry produces the series and is one of its writers.

The rest of the cast (Thomas Lennon, Lindsay Sloane, Yvette Nicole Brown, and Wendell Pierce) are all performing professionally, doing the best they can with the lackluster material they're given. It just goes to show just how hard it is to to write a comedic show well; presumably this show has a healthy budget and could hire decent writers.
