I honestly think the romance is just one step from where it needs to be. And that is someone deciding to freaking reciprocate the feelings of another character. Hinata mentioned she's going to be walking with Naruto after the war. I hope that's in more ways than one, but I don't want them to be all kissing and hugging all the time nor would I want extra arcs where you have to go save a damsel in destress. Does that make sense?!
Add in the feeling that these characters are more than simply missions. Yes there should be a kiss aside from Naruto and Sasuke...but it doesn't need to lead the series into a situation where a couple (say Naruto and Hinata) are walking down the street arm in arm...maybe once in the series.
Asuma and Kurenai was a good example of a relationship in the side they need. Only difference is they need to be actually open about it and not in the dark like those two were.
