This is a must-watched series, I bet. The storyline would be a bit usual like the others' horror and drama series. Nonetheless, the characters act so so great and the setting is really interesting that you will see it spine-tingling and riveting. As it is set in Hawkins at a time of 80's, you can also enjoy the character's suits and (esp: hairstyle) and how hard they try in the series to remind you your 80's. The soundtrack and the 80's songs they chose in the series are out of the world and really fit with the characters.
Also humor and drama can reach your hopes absolutely. The make-up they wear is also inspiring. If you want to feel those things at the same time, I would recommend you.
Nevertheless, I think a bit less of season 3. It seemed nothing happened but the sequels are really riveting and intriguing.
By the way, it's also gory and tear-jerking.
