Bearing more than a distant resemblance to "Gattaca " starring Ethan Hawke and Jude Law, "tropic" is perhaps less original ,unique, than it appears at first time .Sci-fi ,with a few exceptions ,has never been Europa's forte.
Two twins are part of an elite ,intellectually and physically fit for the great future of the conquest of space ;their training is demanding ,be it in mathematics ,physics and sports training ; and there's a mission afoot and only one of the -male and female- candidates will be the chosen one .All that concerns the military project is credible ,semi-doc. And absorbing.
But it's not all good news: turning one of the brothers into a monster with a horrible face after a contamination is perhaps not a good idea ; it does not bring anything substantial to the plot (it's a variation on the "Gattaca " theme) and ,in my book , seems a commercial cheap trick ;besides the character of the mother is embarrassing ,which the actress does nothing to rectify .
The twins relationship could have been an interesting psychological drama without this awful make-up and ,from that point of view ,it's a missed opportunity.
