Sam Neill actually likes Jurassic Park III February 5, 2021 by: Even though JURASSIC PARK III was financially successful in its own right, the film didn't really reach the same level of success as its predecessors. The third film of the franchise carries a 49% rotten rating on Rotten Tomatoes and it seems as if most fans of the franchise don't hold it in high regard. Sam Neill returned in Jurassic Park III to reprise his role of Dr. Alan Grant after skipping out on the second film and the actor feels the third installment is quite underrated, despite having issues with the last ten minutes of the film.
