I got the pile of movies I ordered, and although the sub I ordered isn't exactly functional yet, it's heading in that direction and I hope I have it working in a number of hours from now.
I did watch the movies I bought anyway. I'd crank up the bass and let the 123A-3 woofer on my JBL L100s do the best they can, which is not too bad, but naturally they're not going to do what a sub can.
The assessment I've got out of the 15 or so movies I've watched recently that I bought for sound, is that the best, (mind you, sans a sub) is "Godzilla", the one from '98 with Matthew Broderick. It's a better movie than I thought it would be, although I'm not going to call it great. It's average as the script contains some moments that are, well...corny. Overall, though, it's done well from a sound standpoint. When that lizard on hormones goes stomping through New York, you'd swear it's outside the house. Lots of sound. It's a movie full of action.
If you've got a system that can hit reasonably low frequencies without a sub, check it out. It's pretty impressive.
I think that the Superbit version of "Das Boot" is going to be spectacular too. When the depth charges go off while watching the movie without a sub, I can't hear anything, which I imagine is the result of the 123A-3 not being able to drop to the frequencies needed. The rest of it is impressive, though.
