I have 5 sons. That is more than enough risk taking for me lol. I am absolutely the settled down type, I prefer my adventures (other than the daily adventures with the kids) to be in books or on Netflix :)
Instant love? no. Instant attraction? of course. You can't love someone just by looking at them. no matter how attracted to someone you are, after getting to "know" that person, you might not be able to stand them as a person. No, I don't think there is anything like instant love or love at first sight, just attraction.
Most movies never live up to the books. I find that if I have read the book first, the movie normally lets me down. Of course there are always exceptions. I was quite happy with the Harry Potter movies for the most part (especially the last 2), and then there are movies like A Walk To Remember that I just loved, and the mini series by Stephen King The Stand was pretty good and pretty true to the book as well.
