Lockwood & Co. is useful for English practice if you can already follow natural conversations. The language can be demanding, as characters often use less common expressions and more specific terms. With the dialogue moving at a natural rhythm, viewers should catch most of it, although a few moments may still be challenging. At an intermediate level, the main story should be easy enough to follow. If your English is close to B2/C1, Lockwood & Co. can be useful for building vocabulary range.
