Alternate Character Interpretation: The fact that the same actor (traditionally) plays John the Baptist and Judas opens up whole volumes of speculation, even if the production plays it as one actor playing two distinct characters (John's holy mission was to prepare the path for the beginning of Christ's ministry, then was it Judas' holy mission to close Christ's ministry on Earth?) If they're the same character, than you can have a Judas who began the movement but is frightened of what it has become, or a heartbroken John, his most loyal disciple, following Jesus' orders no matter what the cost.
Awesome Music: There are arguments to be made for, depending on the production/performers, "Alas for You", "Save the People", and "Day By Day", but the one song everyone agrees is amazing is the "Crucifixion/Long Live God" finale.
What, no love for "Bless The Lord" or "We Beseech Thee"?
Thanks be to Thee, my Lord Jesus Christ For all the benefits Thou hast given me, For all the pains and insults Thou hast borne for me. O most merciful Redeemer, friend and brother, May I know Thee more clearly, Love Thee more dearly, Follow Thee more nearly.
Misaimed Fandom: The complaints by detractors of the show's plot regarding the lack of an obvious depiction of Jesus's resurrection completely spits in the face of the fact the show's focus is Jesus's teachings of love, not his life, death, and resurrection.
The 2011 Broadway revival did an event called "Godspell Cast of 2032" which featured child actors in place of the regular cast. Jesus was played by a very young Gaten Matarazzo, who went on to star in Netflix's Stranger Things.
The 2011 revival cast itself had a number of members who went on to star in bigger roles on Broadway and television, including Uzo Aduba, George Salazar, Lindsey Mendez, and Joaquina Kalukango.
Specifically for the film
Big-Lipped Alligator Moment: The "Alas for You" scene comes out of left field, with the Pharisees depicted as some strange metallic monstrosity made of various junk that speaks in a Voice of the Legion. It comes apart and gets taken down as the song finishes, and the incident is not referenced again as the segment goes immediately into "By My Side."
Ensemble Dark Horse: Jeffrey Mylett (plays the recorder, wears the derby hat) has a surprisingly sizable fanbase. Unfortunately, he died of AIDS in 1986.
Harsher in Hindsight: The movie features a lot of dancing in front of and on top of the World Trade Center, but the hardest hit to the gut is in the last section of "All For The Best". The cast singing and dancing on top of the almost-completed North Tower with a spectacular view of NYC behind them? Pure joy. But then the camera pulls back so that we see both Towers, centered and focused, as the cast repeats the chorus: "All for the best!" What starts as a fun vaudeville song about life's joys and sorrows being "all for the best" turns into a haunting gut-punch 30 years later, on 9/11...
Lyrics: "When you feel sad
Or under a curse
Your life is bad
Your prospects are worse...
...Ah, don't forget that when you go to heaven you'll be blessed
:Thanks be to Thee, my Lord Jesus Christ
