I am slowly starting to like this series better and better, the dialogues are strong, the humor is sharp and inventive with many original puns.
Charlie Sheen does a wonderful job with his black humor, and Holland Taylor is sometimes hilarious as his crazy mother.
I sometimes find Alan's character a bit over the top, the nerdiness is sometimes very exaggerated, but in general he does a good job.
In this episode Jane Lynch is back as the psychiatrist, Alan has really tested Charlie's patience with him this time, so much so that Charlie, who clearly wants nothing to do with psychiatrists, goes to see one.
We get to see all the scenes through flashbacks, the short conversations between Charlie and Jane Lynch are great, but all the scenes between Charlie and Alan are also hilarious.
