I've seen the trailer for this movie a while ago and it captivated my attention, so I was interested in seeing this film, but held no high expectations for it.
From the trailer and the poster of this movie, I had an idea of what this movie might be, but I was a little surprised when it started developing into something I didn't quite expect. Not to say it's bad, the storyline was very interesting.
The start of the movie had a great creepy-stalker vibe to it, and as the movie progresses, it really grabbed my attention and I was curious to see how it would further develop. The two leads, Ksenia Solo (Holly) and Dominic Monaghan (Seth) both gave great performances; I also really like the concept of this story. The only issue I have for Pet, was that it didn't feel like it fully developed into anything. Sure, the story and characters were entertaining to watch, but I couldn't help but feel like the movie could have gotten more interesting or added more "events" that took place.
Overall, it's a solid psychological movie. I liked the idea of it, but wish there was more done to it. Around midway through the film, it just felt like things were at a standstill and nothing more was going to happen.
I'd recommend watching it if you have the time, it didn't feel like a waste of time at all. I only wished that there was more done that could have made this movie much more entertaining of a watch, as half the movie didn't feel like much happened.
