um.. samantha and felicity i can NOT decide!
Felicity is definitely my favorite AG movie. I enjoyed the acting and writing in that movie. Plus I love their clothing. I have seen most of the movies. The only 2 I have not seen were Samantha and Chrissa.
I've seen all four (I am not counting GOTY movies) and I have to say Samantha's is my favorite. The casting, the costumes, the way the plot ties to the books so well, everything about it is wonderful.
