Here's an anime you can ignore. It's weak and boring, it lacks action (yeah there is some, but it's quite lame), the plot is nothing special and the main character is a cheap Rambo knock-off, but not as cool and without the charisma of his genuine counterpart. So yes, basically the only things he shares with Rambo are the physical appearance, the attire and being a former special forces military guy. Animation is quite choppy, art is ok on par with other obscure OVAs from the 80s/90s, characters are mostly flat and the soundtrack doesn't shine; there's really nothing in this OVA that makes itworth watching. I can't recommend it because you probably won't enjoy it, it's not good by any means but it's not awful enough to fall into the "so bad it's good" category. I've seen a lot of terrible anime that provided some genuine laughs because they were so poorly made to become fun, but this is not the case. It's just a barely acceptable OVA with little to nothing to offer.
