Is Eliza Doolittle actually a good artist?

I generally don’t listen to generic top 40/chart/pop/radio. Recently I heard her single ‘Pack Up’ and really liked it, and now I am listening to the album.. I think I may be being pretentious but have I gone insane, or is she actually any good? I am worried I might have the brain worms or something… Any opinions? is she just teeny-pop garbage and I should crawl under the couch, and give up, or is she cheery and fresh and quite lovely (which is what my brain is telling me)
