I thought it steadily declined after season two.
I actually agree. It seemed like the show tried to deny its roots...which actually put me off by the time season 3 hit....
No Andorians, changing the look of Vulcans and Romulans, no Orions, Tellerites to mix with the new aliens that were created. Not too mention, changing the uniforms, and taking away the 'fun' and adventure aspect of Trek.
With that said, there were some few good episodes in later seasons.
 
				 
 
		 
 
		 
 
		 
 
		 No TV series yet that has lasted more than a season has ever managed to avoid the natural decay that comes with having been on the air for too long.

		 Really it's just an extension of 'Troubled Second Album Syndrome'. There are loads of artistes who would be better regarded if they'd stopped after album 1, and certainly more than a few (including greats like The Beatles) where even the most ardant fan can see that churning them out eventually wore everybody down and led to fatigue (and eventually a decline in quality).
