(I'll give Ahnold credit for one thing; in nearly every shot I saw, he's not in a key light.)
Millennium angle aside, I think this picture was released at the wrong time of year. I think it would have done better in summer or even as late as Halloween.
At the theatre where I work, the five-week-old "Being John Malkovich" outsold "End of Days" almost every show. And Bond did at least twice the business every show.

A proffessor of mine in collage said something that may apply to End of Days. He said that a genre film is killed when the parody is released. Think monster films, then Young Fankenstien comes out. Boom no more monster films for a while. Disaster films, then Airplane comes out. Boom, disater films move to TV.
If you have seen Dogma then you know it's much smarter and hipper than End of Days. It's like the parody came out before the straight film.
The local paper here gave it an "F" (which I've never seen given to a movie before). It wasn't anything to write home about, but I'm thinking the reviewer must've been offended at something in there. I mean, there are a LOT worse movies that never got "Fs".
The movie didn't look too dark to me, but that may be because the projectionist that night had JUST changed and focused the bulb, and that house has the sharpest picture.
I agree with Ian, I found myself comparing the movie to Dogma as well, which is rare for me - I try my best not to compare two movies of different genres.
I think the lamest thing about the movie was the logic (or lack thereof) of the plot. I was watching Roger Ebert, and he pointed out the part where the priest says the calander was developed by the Gregorians based on the prophecy of Satan coming back every 1000 years. That's so stupid - they made a calander based on Eastern Time back when they didn't even know that the continent of North America existed?! Most of the time when I watch movies I practice "willing suspension of disbelief", but not when the writers are insulting my intelligence
A: 16 to 18 footlamberts 
B: 12 to 16 or 18 to 21 footlamberts
Failure: Less than 12 or over 22 footlamberts 
Anything less than 12fL is just too dim, producing poor shadow detail, desaturated colors and dull highlights. The reason theatres should not exceed 22 footlamberts is that the 48hz. shutter flicker (2 X 24fps = 48hz.) becomes more noticeable at excessive screen luminance. Going to a higher frame rate (e.g., the 30fps of Todd-AO or the 60fps frame rate of ShowScan) would allow much higher screen luminance. Or a 3-blade shutter could be used, at a cost of light efficiency (not practical on very large screens).
