Merlin is a good choice for confident learners looking for more realistic and demanding listening practice. Conversations usually leave enough room to process what is being said. The language mixes everyday English with a few expressions that need attention, so it works best for learners who already have a solid base. There is enough plot detail to keep learners engaged without making the whole experience confusing. If your English is close to B2/C1, Merlin can be useful for building confidence with more complex narratives.
