So I stumbled across this little gem while bored at work. Now I'm the first to admit I don't normally laugh out loud at the tv, but this first series even from episode one I was howling! I love science fiction and this has parts of all the best movies, even the chemistry between the characters are great. Please watch season one and you won't be disappointed. However then comes season 2. Well it just felt like it had plummeted to the bottom of the TV bowl. It's almost like they forgot what they did in the first series. Not that funny and very predictable. I prevailed though and watched series 3, which kinda wraps the whole thing up. Not as good as series 1 but better than 2. Defo worth watching the whole thing tho to find out how it ends.
