I'm going to keep this review short and to the point, just like the anime itself. Wild 7 is a very fun anime to watch, it's definitely not extraordinary, but what it does, it succeeds in pretty well. The story, albeit it seems rushed, was interesting enough to glue my eyes to the screen, to see how it would all turn out in the end, and oh boy was it worth it. All the main characters had a certain charm to them, that really made them entertaining, and seeing them interact with each other, and seeing the way they fought, were some of the highlights of thisOVA.
This anime is very gory and violent, almost absurdly violent at points, but that's exactly what makes it so much fun to watch. Classic violent "gar" anime that really needs some more attention, stuff like this can be rare to find in newer anime.
I would personally recommend Wild 7 to anyone wanting to get more into the gory 80's and 90's OVA's, and people who just want to kill 2 hours fast.

I feel like a good 7 describes my feelings about Wild 7 well. Not perfect or crazy good, but a good older anime nonetheless.
