Here you can find a good show in Kuwaiti dialect.

Most of the videos have English subtitle. Which will be good for you. I have watched all the episode of سوار شعيب and I remember they were good. I haven't watch the other ones so I only recommend for you سوار شعيب. You can find on the channel 3 or 4 seasons. If you have a question regarding these episodes and you haven't find a help from a Kuwaiti  person you can ask me anytime. Good luck.
