The masks we wear MINOR SPOILERS AHEAD
As a person who fell in with the overtly religious crowd and later (but very gradually) fell out of that crowd again, I found the premise of "Rain" very intriguing. I didn't push the DVD into the player with high expectations though, knowing that such contentious themes are often treated with soft gloves by the entertainment industry. Having seen it now, I am happy to say that it is a movie well worth seeing, if you're interested in issues like mankind and morality. The production team certainly didn't hold back on their message.
Other viewers may be left with other impressions, but to me a central message of "Rain" was: if we choose to wear masks instead of presenting our own selves to the world, those masks are bound to crack at some stage.
Other reviewers mentioned quite rightfully that the extremely sudden conversions portrayed, seem a tad suspect - not only in behaviour but also in appearance. For instance, Sadie Thompson's hairstyles change rather dramatically overnight. This is a movie adapted from a play though, and we have to accept the dramatic license that film-makers need in order to secure the viewer's attention for some 90 minutes. If we insist on everything being realistic, movies like these would exceed 6 hours. And due to the already dialogue-heavy narrative, there is no choice but to take a few short cuts.
I certainly do not want to fault Mrs. Crawford's performance as the pivotal character here - she gives a suitably strong performance in my opinion. I can however understand some commentators' criticisms, even if I feel them a bit harsh. A Carole Lombard or a Bette Davis (not to fan the flames of the real-life Joan-vs-Bette animosity here) may have brought a bit more physical swagger to the role, and perhaps saved the film from some of the negative judgements it received back in 1932.
Props to director Milestone and the crafty editors for the memorable "Crawford entrance" near the beginning and ends of the film. It is the kind of cinematic thrill that latter-day directors seem to struggle to match. The soft lighting used on Crawford in one segment of the film, and harsher lighting in other segments, were very effective too.
I found "Rain" satisfying as a cinematic product, and even more satisfying as a film with philosophical substance. The latter is better discussed in the message boards.
