How bad is it? It's a cheap potboiler with lots of stock footage and no sets.
Should you see it? It's not essential. If you want to see a Barry Mahon film, I suggest "Rocket Attack U.S.A." or "The Beast that Killed Women."
This was Errol Flynn's last film. It appears he helped finance this film to launch the career of his 17 year-old girlfriend, Beverly Aadland (it didn't work). Flynn plays himself, except that he's a reporter, rather than an actor - and he narrates more of this film than he shows up on screen. Aadland's character is involved with a man who's smuggling weapons to Castro guerrillas. The film purports to have been filmed during the overthrow of Batista, but much of the footage appears to be taken from newsreels and the original footage is dark and could be anywhere. This was Mahon's first directorial effort and he ended up shooting a lot of soft core porn at nudist camps during the brief period when that could be called "educational."
