Possibly, but more time to breathe would have helped the audience transition. For example, there was so little visual/dialogue cues of just how far the Jorah/Missandei deaths had pushed her to the edge but after all is said and done, it was obvious the writers intended those deaths to be the catalysts for Dany's transition. That's writing. On the other hand, spending more time earlier in the season (a longer season) showing how Dany was capable of the ultimate atrocities she committed (since the writers can't go back and rewrite previous seasons) was also necessary. Her earlier acts across the sea somewhat implied she was capable of such things but they were driven through a pursuit to help others, not the pursuit of helping herself. There's a moral rift between those events that needed to be explained and transitioned in more detail. That's pacing and time.
