OK, so maybe the acting wasn't all that good. And maybe the plot was a little thin. But this is still my 3rd favorite movie of all-time! I may be crazy, but I loved this movie.
And now for some nits:

Jen wears makeup to sleep?

How did Mack get Jen's gun in the hotel room?

How did he disappear from her room later...is he Batman?

The front windshield reappears on the car after it's shot

Come on. Jen's ankles HAD to hurt when she did that backflip from the pillar!

In Pudu station, the lights turn off at 6:33:38. Why not set them for a more normal time like 6:00 or 6:30 exactly?

When Mack surprises Jen at the end, he is out of breath. I don't care HOW fast he is, there is NO WAY he could have made it across in such a short amount of time without her noticing.

One last thing. Catherine Zeta jones = Fathom (Aspen Matthews). The resemblance is absolutely perfect. Picture perfect in some scenes (Like after she swims for 2 hours at the castle...).

For some reason, I was rooting for Catherine Zeta Jones' colleague to bust her and Sean Connery!

The lights at Pudu are probably sensitive to ambient light, not the time. Even if they aren't, they could be set to a different clock, or set to shift with the shifting time of sundown. It wouldn't be logical to flip the lights on every night at 6:30pm. Depending upon the time of year that would be far too early or late.

And I think it's Gin (as in Virginia).
