Firefly is space cowboy kind series which occur in deep space. Nathan Fillion has done justice to the role, and also other cast members are also worth mentioning. Initially, my friend suggested this series in 2015. Though the series had only one season, after watching, you will ask yourself why on earth they stopped such a good series. The relationship among actors is too much touching and you will simply fall in love with them. Also according to the graphics standard of year 2005, the series feels smooth.
