This film really misses the mark. It feels like a low-budget imitation of "The Shallows," specifically the American adaptation rather than the Chinese one, only with two characters stranded on a rock instead of just one, and an Orca replacing the Great White shark. What’s particularly striking is how awful the greenscreen work is; it really shouldn't have been used at all. Those scenes could have been filmed outside, in a pool built for filming, or even with a painted set. The choice to use greenscreen was bafflingly executed poorly. The characters aren’t appealing, the storyline is ridiculous, and the overall appearance is disappointing; there’s not much positive I can say about it. I'd suggest finding something else to watch.
