Not tonight

I started playing Assasin's Creed again tonight. Had it since I picked up my PS3 late last year.
 
The game is fine I guess, but nothing is going on, so much that I want to see it through to the end. And I enjoy action adventure games.
 
So, I guess the question I'm asking is, if I don't enjoy the first one, is AC2 going to change things that much? It got rave reviews I know, but I really don't need another game to pay through at the moment. I'm a stickler for finishing games in order in a series, too.
