Generally I am not a big fan of romance anime, however Toradora! was very enjoyable. I was going to just watch a few episodes then ended up finishing it in 2 days.
Toradora! isn't actually that clichéd, compared to other rom-com's. Sure it's main plot may seem a bit at first but once you get into the anime you'll see. Also, I feel it has some of the best characterization in anime.
