Poseidon

What was I thinking?

No, wait; what were the makers of Poseidon thinking?

Dialogue tainted by every cliché in the book. Typecast characters I didn’t care about, including a jerk nicknamed Lucky who dies and a screechy child who regrettably survives, although not without constantly wandering off to become imperiled. Ultra-linear, by-the-book plot. Kurt Russell looking and acting like he just finished scarfing down an entire uncooked meatloaf.

Some of the special effects are moderately absorbing, but nothing that hasn’t been already gaped at in Titanic nearly a decade ago.

And there’s trouble in the cards, Poseidon people, if your movie packs the opening-day 8:05 p.m. show in Manhattan only half full. There were more people lined up across the street to see Guns N’ Roses at the Hammerstein.
