Justin Turner’s review published on Letterboxd:
Battle at Big Rock is a short film that Colin Trevorrow directed that plays off the events that concluded in Jurassic World: Fallen Kingdom.
It appears they are setting up the next film to be The Walking Dead meets Jurassic Park in an apocalyptic atmosphere. While the short film is only eight minutes long, it maintains that horror vibe. The effects on the dinosaurs looked good, and the final sequence with the T-Rex was entertaining.
Love the post-credit scenes too with how they display the dinosaur-human relationship in modern society like oil and water.
