That still sounds like just one dimension to me. For two dimensions, you would need “mild very positive emotions” (contentment?) and “intense slightly negative emotions” (overpowering nostalgia?).
One way to get around this is to classify emotions into active and passive (or high- and low- arousal), where, for example, anger would be active/negative, and grief would be passive/negative. Like the emotion diagram I’ve seen around the internet lately:

That being said, it’s still interesting how vague emotional classifications can be.
