Granted, I'm basing my star recommendation on memory only, and in the context of being an 8-year-old kid watching this film during school in the '70s (so I knocked a couple stars off for the film potentially being outdated). However, this film made a huge impact on my life. It's hard to watch, graphic, and raw - and very important. This is no watered-down version of man vs. animal, or the cruelty that we can inflict. As such, we were given a choice whether to stay and watch the film or leave the classroom while it ran. I'm glad I stayed, as (as you can tell) the impact of the film has stayed with me to this day. I recall the scenes of the baby seals being clubbed, a giraffe (maybe?) who had a spear thrown at her (as I recall it was a female...) which stuck in her neck but didn't kill her until days later after a long chase while she slowly bled to death. An important work with an important message, which sadly is probably still as relevant today as it was 30 years ago.
