Having never heard of this film as it was released over forty years ago and seems to be a rather smaller scale independent foreign Spanish film. Had little expectation and with an open mind, the film is definitely a mix of several things which in general turns out to be quite bizarre yet intriguing.
There is a lot more nudity and skin than expected but given the premise, it isn't too far fetched. Also for some strange reason there is no dialogue spoken in the film which was entirely confusing. We see the characters making sounds with their voices and are able to laugh yet for some reason they cannot speak. This was never addressed as to why they don't speak which took away slightly from the film but it ensured us to pay closer attention.
Such as in the beginning when we see these three characters wake up in an island, we don't know who is who or their names. Yet around 10:40 the blond male pulls out a wallet and sees photos of him and the blond woman with a quick subtitle reading "to my dear brother". This is how we find out the woman and that male are siblings. They are also dressed similarly as if they are attending a party together. It's also assumed the other older man was in another photograph with them, that they all knew each other. As we assumed they had lost their memory.
Then about 30 minutes later we see these character walking in an abandoned house and the brother finds a dog. The dog becomes part of the story and is one of the highlights. While the woman is the clear standout.
Considering no dialogue lines are spoken, these actors are very amateur as both haven't had many previous work. The older man had more work.
There are some quite graphic animal violence further in the film such as them killing these animals (nothing explicit shown on screen) for food.
The very ending is quite predictable and we wonder as to why the brother didn't do it much earlier on as he had many chances. We knew the older man wasn't going to last.
Overall this is quite a bizarre film blended with different genre mixes. Somewhat frustrating how they don't speak but it's perhaps for the audience to pay closer attention to detail. Something seems to be happening at all times which ensures intrigue.
