Since the author realized that he's going to make this run as long as he lives (or as long as there's interest) it has become a formulaic, and repetitive story. It basically runs like this:

-Training
-Fights
-End fight filler
-Rinse and repeat... FOREVER!

Of course there are good fights with the occasional serious Takamura title match. However, there are too many filler fights (Ippo title defense and Kamogawa gym underling matches) to keep things interesting during volume 50+. With how things are going, this manga will stretch forever.

It is likable though since I have lasted up to v60 and still going but I have found myself scanning the post and pre-fight fillers as well as the filler matches in hopes to get to the more important matches. This basically sums up how HNI is going.

Unless the author keeps things interesting, I will simply skim through the repetitive and formulaic discussions/fights and go through the important matches.
