I know very little of it follows the manga (if anything). I watched the first 20 eps or so and a bit of the Mist Village story arc but I just couldn't get into it.
Does it get better? I was a huge fan of the original series and really loved the Boruto movie and one-shot mangas from Kishimoto (which I did watch the anime adaptations of).
I really want to enjoy this series. It has a lot of cool concepts. Boruto and Sasuke's relationship, future ninja tech, Hokage Naruto, etc. It seems appealing, so I'm hoping it gets better later on.
Yeah, it gets much better. The first arc of Boruto is really boring.
Right now, Boruto just got done with a good arc and we're in a pretty great training arc where Boruto trains with Kakashi and Sarada trains with Sasuke & Sarada.
Like Naruto Shippuden, I would never recommend you watch every episode. You just need to know which episodes to skip or watch.
-----------------
Depending on whether you want to see Boruto and Sarada develop their skills a little more, I'd tell you to just finish the Mist Arc. It ends at episode 32 anyway. Or at least watch episode 30 for a great Sarada fight. Or skip it if you prefer. It's not thaaaat important.
I'd say skip to the Genin Graduation Exam Arc and Mitsuki's backstory episode (episodes 36-39). I say those are must watches.
The new Team 7 has a decent first mission with some cool teamwork and it's only two episodes long(episode 40-41).
Watch that and then watch the Chunin Exams Arc (episodes 51-66). I know that you already watched the movie but the anime version expands on everything and makes it better. Hell, the Momoshiki v Naruto & Sasuke battle was done even better in the anime.
From there you'll have to skip again, to episodes 71-92 for a Mitsuki Arc but while it's got decent stuff there and the death of an important character from Naruto, it was too long for what it was trying to do.
So you can skip that. It's not that important although you'll miss seeing a few cool things.
Definitely watch the Parent-Day Arc. Episodes 93-95 are a must watch especially to see Naruto and Sasuke with their daughters.
Also tap episode 97 for a character episode on Shikadai and his family.
I don't want to overwhelm you so let me know if you want more recommendations past this.
