Ok, so i realize that this is quite a premature review, but after viewing the first six episodes on Sky during a marathon sunday session, (have to love sky plus) i had the overwhelming need to blab and yell and cajole anyone and everyone on the wonders of SGU.
The second series does not disappoint, it thrills, and captivates. The creative team have completely superseded their first series they have developed the characters, adding layers of meat to their bones, throwing in both overt and subtle variations to life on board the Destiny. They broadened the scope of alien threats, delved expertly into the fragile human side of its leading characters, not only showing us their warts but what lies beneath (ugh). Finally there is a Sci fi show willing to giving the audience something to revel in, I have nothing negative to say, except that i want more, more of the same please, more surprises more darkness more fragility more special effects.
This is without any doubt the best sci fi show around. It trumps those that have preceded it and if it continues to grow as it has done, it shall be remembered for a very, very long time to come.
SGU for ever.
