There's enough real water in 'Thérèse Raquin' to float a row boat, but not a drop of sexual tension. Without high heat and funky musk, this wannabe erotic thriller starring Keira Knightley is bloodless and all wet. Too bad. It makes for a dispiriting Broadway debut for Knightley...she never finds traction in this choppy adaptation. Helen Edmundson's script is filled with microscenes that start and stop without impact...Director Evan Cabnet relies on disembodied voices and eerie sounds effects to show the pair's haunted minds. Just in time for Halloween, 'Thérèse Raquin' and the A-list actress playing her have found themselves stranded in a corny spookhouse. Scary.
