We Brits are witty and smart!
Yeah - the beginning part was a little slow - simply because it took a while for Bart's character to kick in I think. I also found Asmira a little dull - she got more interesting towards the end, but it took a while. In a way I wish we knew more about her, so you could come to care more for her character and her choices.
I kind of love how Bart gets so attached to humans lol - and will do his best to save them even if it means it puts himself in danger - despite his protests to the contrary. Bless him.
