I thought it was... OK. A little too much Eleven ex Machina for my liking, and I got very tired of some tropes being repeated too many times (they're creeping away and bump something / stand on something). Took a while to get used to the new voice cast. But overall, it was enjoyable, and I liked the new monster.

I really enjoyed it! It took a few episodes to get used to the new voice cast, but I thought Nikki's addition was fantastic, and I loved how they really took advantage of Eleven's powers as the series went on. Really dug it, and I'd be cool with another season.

I only just started it, so I still have a bit to watch, but I'm actually liking it a lot more than I anticipated. I don't think it was necessary by any means, but it's pretty fun and definitely fills the void left by the show.

I've only seen a few episodes, so I can't really say for sure but yeah it just feels too unnecessary to really stick. Think after the end of the main show, it's hard to jump back into the world.
