Toradora is a relatively good anime. (I personally didn't enjoy it) It has a strong plot, great characters, and unique situations for the characters to develop. It is above regular romance anime in that regard.

The only caution I can advice is that is you are against things that look like pedophilia. There is no pedophilia in the show, but taiga does look like she is around 8, and to see her acting romantic with other characters that look like they are 29-23, might be disturbing for some. I personally didn't mind it until the kiss scene at the end.

However besides that one flaw, the show has some good merits, and while I didn't enjoy it is was indeed a really good anime, from a critics perspective
