While it did feel a forgivable amount rushed, I truly don't understand the negative reaction. SPOILERS
The fact that the Eliot monster didn't show up earlier, the fact that the seam was found so easily (unless i missed something), the fact that all the hedges came together so fast and inexplicably (although that would have been boring to watch), and the fact that Eliot healed from his injury without magic while Julia had complications with magic.
These are the rushed aspects of this episode in my opinion, but the show for me has always been about more than the actual plot. If you just go by the story, it's overly complicated and things kind of pop out of no where anyway. Where the show shines is very similar to how sense8 shines. It's about relationships and emotion and i felt this episode did incredible in that sense.
The ending with Q was a little rushed but they had already gone into his mental illness before, and as someone who truly struggled with suicide for a good chuck of his life as well, i felt they did a good job portraying it in this episode. Even though I'm happy and am doing much better, as Q was, I still have a strong sense of things not being good enough. To have true doubt about yourself and your motivations after going through something that must have put him into shock can only be natural. Plus they were going off the idea of a life review when you die concept, which can only truly be an emotional experience as moral judgments as to what you did right or wrong in life will always be unfulfilling and ambiguous.
