I hope this is his swan song. Patrick Stewart is amazing, and I love Captain Picard, but he's not Harrison Ford. The franchise will be fine without him. We don't need to play out Too Short a Season in real life
Three seasons of PIC were already a mistake. The only good thing coming from it is the possibility of a Riker cooking/baking show (which I would totally watch).
In rewatching the original series and TNG thereafter, the consistent factor, regardless of the early special effects, was the scripts. The dialogue was always great. In ST: Picard, the dialogue is trash.
2 seasons were a mistake and by far the worst trek seasons from any show, the third season while being massive fan service was just what I seemingly wanted as I loved every second and was a great ending to the TNG crew
I think the difference between Stewart and Ford is that Stewart seems more to be doing it because he enjoys this character. Ford seems to be doing it in spite of his feelings.
As long as Stewart is still having fun, I'm happy with him continuing as long as he wants.
