If you love comedy TV show. I recommend you to watch " Stupid Cupid" on Netflix or other platform. It has many easy word in Thai. 

Hi! Journey the Series is a show available on youtube. It's about travelling in four different parts of Thailand. You will see destinations in many cites and local culture. In the show, the girl named Natt and she is a real Miss Thailand 2015. She is also top 10 of Miss Uniververse. The boy with glasses is a real singer. He won the 1th season of the VOICE Thailand and he was only 16 then. He is popular singer nowadays. The other guy is an actor in some Thai drama. They play the real characters in this series. They speak slowly and clearly. I think this show is really good for beginners. Another one is Master Chef Thailand, also available on youtube. If you are interested in cooking, this is one of the best shows you can practice your Thai. You will learn more about Thai food too. I hope these two shows work for you. Mallika.
