I have no idea how some people give this film low marks, everything from the scenery to the interaction between cast and animals is breathtaking. I was enthralled throughout this emotional roller-coaster thanks to the trainers of Mij the otter and the acting of the two lead roles, i watched seven samurai the night before this, so it had a lot to live up to, and it was one of the first films in ages where i didn't look at the time once, i was so happy watching this man and otter co-exist that i didn't want it to end.
There are emotional extremes in this film, moments of tearful joy and moments of terrible sadness, so be careful if watching with kids. For a 1969 production, I cannot recommend this enough, i watched a free copy with a newspaper, and i will be buying the full DVD very soon and I'm 24! Thoroughly impressive editing & acting makes this a film that will stay with me till the day i die. And dammit, i want that otter !!
