"One-Punch Man Vol. 2," by ONE

One-Punch Man, Vol. 2, written by ONE and illustrated by Yusuke Murata, stars Saitama, the titular, "One-Punch Man." After years of training, Saitama has become so powerful he can defeat virtually every enemy with a single strike. There's just one problem: according to Saitama himself, "overwhelming strength ... is boring."

This particular volume of One-Punch Man features the, "House of Evolution," (an organization whose single focus is the artificial, forced evolution of humanity), the, "Paradisers," (a group that doesn't want to work for a living), and Speed O' Sound Sonic, a super-fast ninja for hire.

Pros:

• The story is still compelling, and Saitama has a number of great quotes in this volume.  One of my favorite (unintentionally) motivational quotes from Saitama is: "Human strength lies in your ability to change yourself!"
• Murata's draftsmanship is still on-point, and does an admirable job portraying the speed and strength of the characters featured.
• The "omake" / bonus chapter adds yet more backstory that is not featured in the anime.

Cons:

• Though I understand why the sound effects had to be in English, I was often disappointed when they were either abbreviated (eg when tremble became "trmbl" on page 177) or they were splashed out over two pages and ran counter to the flow of the comic (eg the "swooooo..." on page 158 and 159). 
• (nit-pick) This is more an annoyance with physical media than the comic itself, but I sometimes found that details would be lost in the binding of the manga, especially in two-page spreads.  I can't help but be annoyed by this since I know it wouldn't be a problem if I purchased the digital version of the story (i.e. via Kindle / Comixology).
• (nit-pick) I don't mind the "villain of the week," format of One-Punch Man, especially given that: 1) the characters are interesting, and 2) I know that larger plot arcs are coming in future volumes.  I could imagine how this format might start to get stale for a reader who came into the series "blind," however.

Conclusion:
The contents of this volume are all (more-or-less) covered in the anime.  With that being said, I still think this volume is worth reading for the additional content you get in the manga.  Also, you get to see a version of the story that is closest to ONE's original vision (other than the webcomic OPM is based on, but that is not particularly easy on the eyes).

Final Score: 
8.5/10
