Mercury Pookkal was advertised as a film "like Missiamma".[2] Indiaglitz wrote "Stanley needs a pat in the back for thinking out of the box. Unfortunately towards the second-half needless stunt sequences and couple of songs certainly stems the flow of the brisk screenplay."[3] Rediff wrote "The simple plot had all the potential to be a great film. But Stanly [..] stumbles in the narration and comes up with a pathetic ending."[4] The Hindu wrote "Stanley's treatment in `Mercury ... ' shows more maturity and class than his earlier films."[5]
