Actually on the whole I liked the "extras" almost more than the film. One thing that entertained me was the inclusion of several scenes that were cut - because there wasn't a one of them that didn't desperately need to have been cut! So all hail to the editor(s) on the project. The U2 video was cutely tongue-in-cheek as well.
I think I may have missed important references (not to be confused with nuances, here) due to never having played the actual games - but things were pretty clear, even so. Lots of John Woo/Chow Yun Fat hommage, a nod or three to Ray Harryhausen, some decent FX, and much more of a plot line than I'd ever anticipated.
Oh, and the thing that motivated me to post in the first place: even-handedness in the gratuitous shower scene department! We are treated both Alex West and Lara Croft conducting their toilet - saved from anything beyond a PG-13 by a conveniently placed table-top and a towel, respectively.
Most delightful surprise: Chris(topher) Barrie playing Hillary the butler. And damn didn't I want to look for a silver "H" on his forehead after I heard the character's name. Heh.
