When I first caught wind of the redundant "sex thriller" Obsessed, my first reaction was to adopt the voice of a blaxploitation announcer and Twitter things like "Bang! It's a black-on-white cat fight you KNOW is outta sight! Look out for the affirmative action Fatal Attraction, baby! Obsessed!" I walked in expecting a base, push-button and knee-jerk story of "white hoochie vs. black wife" story ... but unfortunately the movie turned out way too plain and generic to bother with such immaturities. Had they "trashed" it up a little bit, then Obsessed could have been a grade-A B-movie worth laughing at and cheering with. As it stands, Obsessed feels a lot like a refugee from the Lifetime Network that just happened to have a budget.
Idris Elba (who delivers a performance better than the movie deserves) plays a very successful investment banker named Derek who catches the eye of a pretty new temp (Ali Larter) called Lisa. But Derek is quite married, you see, and rather happily, as would you be if you got to sleep with Beyonce Knowles every night. But that doesn't stop Lisa from (ever so s l o w l y) getting under the skin of poor Derek, and before too long we're dealing with a very basic yet powerful case of, well, obsession. No matter how many times he professes his love for wife Sharon, the tantalizing temp just keeps on flirting. Heavily, shamelessly, redundantly. After about an hour of altercations between Derek and Lisa both predictable and obvious, we finally get into the Act III catharsis, which is when the frequently-dormant Beyonce gets to stand tall and kick some serious booty.
