A Martian Manhunter story I never thought I would see
26 January 2016 | by (India) – See all my reviews

Wow... I mean 3-4 years ago, u'd never think you'd see a story about White Martian vs Green Martian in live action, but I guess a lot has changed in those 4 years and the result was excellent television. .... In this episode, a lot happened. Firstly, we get to see the back story about J'onn J'onzz that there was a war between his people and the White Martians and his people lost and were killed. So kudos to the show for handling the emotion behind it really well and it didn't look forced at all. .... I have to admit VFX effects of this episode were stand out and really really well done. The flying and the White Martians scenes were just outstanding and scary at times as well. I did miss Maxwell Lord in this episode, but a lot was going I can understand that they left him out after last week's cliffhanger. Lastly, Adam Foster returned (Cat's son) and whatever portion of the episode is spent in repairing their relation was really touching and just amusing at times.. So overall.. great television and really well done. P.S. LOVED THE CLIFFHANGER ....I have been so excited ever since they announced BIZARRO. I loved Smallville's version and now she's finally here...... AAAHh!!! NEXT WEEK...such a long time to wait..ah well..
