Show is getting old and tired
8 May 2017 | by carlottaelandSee all my reviews

If you read the caption for this episode, you probably don't need to watch it. If you're a fan of the show, you could write this yourself. The whole series is showing its age. Characters are flat and stale, some are more annoying than ever. Sheldon, for being so smart, doesn't learn much. Leonard stutters and stammers his way through each scene. The ladies manage to keep it fresh, although Penny seems to flounder. I hope this is the last season. It's sad to see a once fresh idea go stale.
