I was excited to watch the movie and see closure on the plotlines from the series but unfortunately that wasn't the case.
The over-formal language, interspersed with the raucous language from the series was a poor fit and I occasionally struggled to understand what they were actually saying.
The preachy overtones in the script didn't do it for me and I wondered what had happened in the intervening years to make everyone find God... Hallelujah etc.
It's worth watching, just don't expect too much.
