Which season do you think the best season of the Fresh Prince and which season do you think is the worst season?

Best season in my opinion is season 3, that is when the show was at it's creative peak.

The worst season in my opinion is season 5, not that is what's that bad, but not as good as the other seasons.

After thinking about it, I would have to agree: season 3 is the strongest, season 5 is the weakest. On the whole, I think the first 3 seasons of the series were much stronger than the final 3.
