Brilliant episode! my third fave episode after Almost Got Im and Feat of Clay and won an emmy as it deserved it.
The writing is brilliant from the ingenious mind of Paul Dini who made a better version of a campy character like Mr Freeze whom i remember back in 89 when i was 8 seeing him on that show and read the comics but this show made us feel bad and feel emotional with Mr Freeze.
Action packed, emotional and quite unique even in it's brilliant screenplay.
