The heartwarming relationship from a father and his two adult sons is so touching and encouraging in this deteriorating world. Lightened up with so many witty sense of humour. Appreciate so many great quotes came with it. Very entertaining. Though it would have been much better if Don did not leave his hair long and Charlie did not cut his hair short in the latter seasons. But adoring Alan’s character. Such a wise young-spirit dad character. I had an exceptional wonderful loving dad on my own, but really would not mind to have Alan as my dad too. Kudos to all main actors for blending so perfectly into their cast characters.
