It is the solid attention to details and the lack of spoon-feeding that impressed me in Aarkkariyam (Who Knows), a slow-burning drama with a hint of mystery thrown midway. Biju Menon one-ups (as he seems to be doing after every other film) as he shines in a character at least two decades more than his real age, playing a father to a daughter who he loves to the moon and back. Both Sharafudheen and Parvathy play their parts really well, and together the performances enhance the overall appeal, not to mention the vivid shots. **7 stars**....
