Typically I don't think that documentaries are best served by having a narrator, but I do believe that _The Hydra_ would be an exception to that. It probably should have had a narrator but didn't. It also probably shouldn't have lied about its content in the synopsis. The subject matter is so interesting to me and mine, that the group I watched it with was all very disappointed with the delivery. The format is _The Hydra's_ failing. _Final rating:★½: - Boring/disappointing. Avoid where possible._
