Mid-2019 is actually the first time I have even heard of the 1991 movie "Strays". Being listed as a horror movie, and with me always having loved cats, of course I had to sit down and watch it as I had the chance.
Now, the word 'horror' might be a bit too much to use about "Strays". It wasn't really particularly scary. Actually, when you step back and look at the storyline, then it is actually a rather silly script and storyline. I mean, a family moving into a house and find themselves terrorized by a pack of stray cats. Sure, it was fun to watch. But realistic? No, not even in the least. Especially since humans are far better equipped for handling themselves against felines, so it made little sense that the cats could cause so much havoc and distress for the family members.
"Strays" was definitely a campy and cheesy horror movie, but that was also what made the movie watchable. It was such an outrageous storyline that you just wanted to keep watching and see what happens next, and see how humans are outwitted by cats. Yeah, so very, very realistic.
The movie actually was surprisingly enjoyable and entertaining for what it turned out to be. But it is hardly a movie that you'll watch more than once. I hadn't heard about it before 2019, and I doubt that I will ever sit down to watch it ever again, as it just didn't have enough material to it to support multiple viewings.
The acting in the movie was adequate, taking into consideration the limitations of the script and storyline.
All in all, a mediocre movie with some watchable value to it, but hardly an outstanding movie in the horror genre.
