Irumugan is definitely a watchable action drama sci-fi thriller. A little more care would have made it a superb watching experience. The believable factors in SCI-FI movies are always a worrying factor for Tamil audience, but still there are flaws with what Anand has set to his Irumugan. Harris saves a lot of dull moment with his BGM. To me this is his best work after Thuppakki. Nayanthara or Nithya Menen does their part well nothing to rave about as ppl say.
