Don't waste your time. If you really wanna watch, just watch the first and last episodes cause the rest are just fillers.
I'm a HUGE fan of the HSM franchise was so disappointed when I found out they're making a series of HSM instead of HSM4. But since I love Disney I decided to give it a chance and I'm glad I did. It's quite cringy but it's a feel-good young adult musical drama series. Also some songs are quite good.
Most people bash this show due to the acting of the girls but come on it wasn't even that bad for a group of singers. Although I'm not a fan of the ending I really enjoyed the series from start to finish. It has the "who is the culprit" element to it and you'll either root for them or want all of them to die lol.
