A little let down....

Rating: 5/10 (15 June 2020)

Id seen the previews for this a month or two back and was really looking forward to the movie. The story line was ok, but I found the acting to be terrble. Paul (Delroy Lindo), IMO, overdid his character there. We were supposed to believe this was a tight knit group, but I didnt get the feeling they were really friends at all.
Also, and maybe I missed something: why were the younger versions of themselves played by the same actors, looking almost the exact same as they did in Vietnam, as if they hadn't aged in 30+ years?
