Even my family, who are not into the unCivil War, were mesmerized at times, and never once asked to leave (what a change!) Certainly 4 hours (with a 15 minute intermission) might be too long to some, I thought it was way too short! I'll definitely buy the DVD. Gods and Generals is a phenominal movie.
Plus, the local SCV chapter was in attendance, with men and women in period dress - the movie was more than a movie - it was an event.
