I've seen this series so many times, it feels like I know it by heart. Still, I bought Blu-Ray for simple convenience of having everything in one spot and in high-def.Short short desc of the show: Future. A band of mercenaries flies around in a ship that has a glowing b*tt (thus Firefly) and does stuff for money. Not always nice stuff, and that's your 1st clue that this series is different than usual good vs. bad kind of stuff we get on regular TV.Characters are beautifully created, with stories behind them that you can relate to (well, some of 'em). Story is always interesting and rarely you will look at the first few minutes and say "I know how this is going to end.". Main character is balancing between goody-goody and ne'er-do-well personality.Somebody already did a great job by doing a review of the series, so I'll keep it short and sweet: if you like UNIQUE and HUMOROUS stuff, here's the best deal you're going to get anytime soon! BUY IT! :D
