HaventGotALife I agree that the "ensemble" became "Stewart/Spiner/Dorn." Not to the extreme that it became "Shatner/Nimoy/Kelley" on TOS but close.
I disagree. If you take a look at the last few seasons, sure there are Picard/Data/Worf episodes; but there are also Riker and Troi episodes in roughly equal measure. They might not be as POPULAR, but they are there.
It was Crusher and Geordi that got the short shrift of attention, but I thought the ensemble feel to the cast was always present.
It was the movies - and Stewart and Spiner's egos - that changed this dynamic forever.
