There were a few issues.
In the book the trackers go into the Tributes left arms, in the movie- the right. I guess it doesn't really matter plot wise, it was just something I noticed.
In the movie Katniss doesn't go deaf in her left ear and Peeta doesn't loose his leg- both ailments that matter in the second book.
Katniss gets her pin from the unnamed Hob woman in the movie but in the book she gets it from her kind of friend Madge. That will matter in the second book too because of Madge's Aunt.
In the book, the flowers Katniss puts around Rue are Yellow and again, in book two this matters during Peetas alone time with the game makers.
No avox girl, no sleeping potion, no scary eyes on the mutts, very little love in the cave.
Being a lover of the book it was great to have visuals from the movie, and the movie was very well made. The little bit of Video Production knowledge I have could see the lighting and filters strategically put into some scenes to make the pages of the book actually come to life! (for me anyway).
Overall I loved it, but I hope the things they left out in this movie don't impact the second too much.
