Liked it, would even like to see a sequel.
2 May 2018 | by terrencepatrixSee all my reviews

More than an adequate sci-fi mystery thriller right here. The plot is quite simple but there are definitely some unexpected twists throughout this movie and an ending I didn't see coming.

A professor is going off in search of an area that both his parents and his sister disappeared in decades ago only to go missing himself. A few of his students along with a sibling and a friend take it upon themselves to go in search of him and find themselves trapped within a cave with some mysterious properties. They soon discover that time passes much slower inside than outside and that years have passed on the outside. I can't say anymore without spoilers, but you probably won't see it coming.

This movie has a moderate budget and uses special FX sparingly, but when they do they're done well, and the set is put together quite well. The acting is mostly adequate, not spectacular, and some of the dialogue is delivered in a clunky way. One of the leading female actors is actually pretty annoying throughout much of it, screaming out her lines, but I'm not sure if it's due to the actress, the writing, or the direction. It's forgivable though.

I found it to be an enjoyable and easy to watch sci-fi flick. Recommended for sci-fi fans with moderate expectations.
