Having to watch way more movies lately with the pandemic, I find a lot of movies I've never heard of or am not familiar with. I'll read a description of the movie first than look to USER reviews to see if I'll watch (critics look for a masterpiece while I look for exactly what a movie is supposed to provide-entertainment).
Calvin Marshall was ok. It passed the time for me. Yes there was the usual formulas, cliches you see in other movies like the underdog trying to defeat the odds, romance develops between 2 people than they face adversity. Nothing struck me as special about the movie but I can't say I was bored either. By the way, the lead character played by Alex Frost, really reminded me a lot of a young John Cusack (Say Anything?) especially looks wise.
I could probably find better movies to watch but I could probably also find worse too, thus the 5 rating.
