**The primary driver of trader sentiment for "Heart of the Beast" Rotten Tomatoes score is the limited early critical sample ahead of its September 25 wide release.** With only one published review (7/10) and festival screenings just beginning, the market reflects cautious optimism around a mid-70s Tomatometer based on preview reactions highlighting the emotional man-and-dog survival bond, Brad Pitt’s vulnerable performance, and David Ayer’s assured direction of the Alaskan wilderness setting. Traders are watching for additional reviews post-premiere and San Sebastián screenings, as Ayer’s mixed track record and the familiar genre formula create uncertainty about whether strong word-of-mouth from early audiences will push scores higher or settle in the low-to-mid 70s range.
