As we all know, All Good Things... includes the huge error of the future Enterprise being able to see the initial formation of the spatial anomaly after they've scanned it (the anomaly grows backwards in time so there should be nothing when they go back to the Devron system). Was this a goof on the part of the writers or did they realize it but just felt it wasn't that important (the future anomaly was "close enough" to when the scan was performed; the anomaly being smaller than the other time periods was most important).
I think it would have been cooler if the episode opened with the future crew encountering the spatial anomaly in the Devron system. Then the future Enterprise would try to close it but in doing so, they create it and start everything. Then the rest of the episode happens. When we see Picard in the future timeline, he must convince them not to close the anomaly and to take the ship in (with the other two in the other time periods) to destroy it.
