I am guess that this film had such a low budget, they could only afford the kraft services and Carmine from Lavern and Shirley.
The acting wasn't bad if this was a church play, but I would suggest watching a You Tube video on how to act for the camera and how to direct a camera for that cinematic shot and not act for the stage.
I'm guessing the cast was made up of local church volunteers rather than putting out a casting call for semi-professional actors.
I do applaud that this is a Christian film and they made it to give the gospel and share a testimony but if its poorly done then who will watch it beside a few festival judges and church members with a handful of close friends and family.
I accredit the actor Levin playing two roles, that took a bit of study
Hey, I made a dozen of so bad films too. The goal is to learn and get better. So keep going, study You tube( I did) practice making shorts. Watch more films ( Not just Christian) watch academy award films with the sound off and ask questions on why the camera moves a certain way or why its placed where it is. Watch horrible films , become a critic and know why they are horrible.
Read screenplays and learn to write ( I do) Have friends who will tell you the truth. ( it hurts but you will get better) I pray the Lord blesses you to make more.
Shalom and God bless.
