Right now, Rambo: Last Blood sits at a 39% on Rotten Tomatoes, which to be honest is basically in line with the previous Rambo movies, with the exception of First Blood, which enjoys an 86%.
So it doesn’t look like Rambo: Last Blood will be a revival for the character in the way Creed was for Rocky, at least not in the critical sense.
Overall, things aren’t looking good on the critical front.
Maybe we can hold out hope for Sly’s prequel idea.
