the last episode of season 2 was especially bad, even natopedia makes note of it

It was the final episode written by Maurice Hurley, who originated the idea and wrote the first draft of the script… “Shades of Gray” is widely regarded as the worst episode of the series, with critics calling it “god-awful” and a “travesty”;[1] even Hurley referred to it negatively.
