I dont mind a love interest. My problem was the status. Sakura was classified as main character, main heroine, yet she didnt do squat for majority of the series. When she does, its overly dramatic in romance.
That was, sadly, a problem with the series in general. That manga focused way too much on Sasuke, to the point he seemed more like the protagonist during certain periods. Then Naruto himself started getting downright weird about the Sasuke issue and started feeling crushed under the weight of the "bond" theme
Also he has a very weak mindset making this manga a weekly isn't a smart choice ether.
Not a lot of choice, there. At first glance, this seems to be much in line with what he'd done previously, a shönen action series. Which means it's probably going to have a lot of page space used on fights and a lot of meandering, meaning the plot would feel like it was going nowhere fast if it came out monthly. Basically, it would have the problem Boruto sounds like it has. Could you imagine if Naruto came out, with no changes to how it was done, on a monthly basis? How many people, here and elsewhere, who kept up with it in its heyday would have lost interest?
Also you wanna brilliant Sci-fi samurai manga I have one word for you GINTAMA!!!
I've heard positive things about Gin Tama, but I mainly skipped it because it's the same length as Naruto. See also, Bleach and One Piece, the latter of which is even longer with no signs of stopping. I think I just don't do big, epic length manga anymore after everything that happened with Naruto. Once they get past two hundred chapters my brain just starts weighing whether it's worth putting in the time.
