Everything is in the Title: I don't see how to justify a $10 price tag for this DLC.
I picked this one, because user comments on metacritics made me thought if was the best of BL2 DLC's: I now hope I was wrong.

So far, after finishing it, here's what you'll find "inside the box":
- Some quests: No, it's not "sidequests aplenty", it's "A short main questline with some side-quests".
- A few arena battles: Just easy and borring "content".
- A handful of races: You'll have to retry them because of bugs with invisible walls on the map.
- Two new bosses: They say "including", but in fact, it should have been "Just two new bosses". Moma just died on first attempt with some rockets, and I had to Google the fourth (Blimp) to remember what it was.

It's not worth $10.
