I really liked it. It did get tedious after playing the same scenarios over and over. But overall, I liked the concept and how you learned throughout the game how each character reacted in situations.
From what I gathered Vivica is not very useful in fighting, but her blunders sometimes work out in situations. Rodney can fight, but his brashness gets him into trouble and he is not good at thinking through situations. Phil and Ash seemed pretty average in most retrospects. Sydney, well, she is just a boss at everything.
