seems like Jesus just gets tortured the whole film, is that accurate?

Not really, it covers the 12 hours leading up to and including the crucifixion. Jesus' time spent in the Garden of Gethsemane, his betrayal, arrest are some scenes depicted from the start of the movie. The suffering Jesus underwent is graphically depicted yes, but in a respectful, accurate way and not gratuitously. There's spiritual aspects throughout that make sense if you've read the Bible as well. So yes, there are essentially torture scenes, but the overall theme is not just torture. That would be oversimplifying it.
