Upside-Down Tomatoes

Checking in on my tomato experiment, 2 months now growing upside-down in buckets in my backyard. The idea is that tomato-lovers without ample cultivation space can still grow their favorite fruit. And I read online claims that in the bucket, the tomato plants are less susceptible to pests and disease.this is what I've ended up with. what'd ya think?

To be completely honest, these tomato plants have not been as pampered as their Right-Side Up kin--they receive less sunlight because of the walls in the back patio, not to mention the shade of the bucket! I am also dubious of how much water their root balls are actually receiving. Current results are scraggly, disfigured plants with small fruits.
Maybe it's too early to give an overall assessment of the experiment, but can you see the skepticism on my face? Perhaps I should not be too harsh; I'll be certain to give a detailed account of their flavor when ,and if, they ripen.
