On the whole I really enjoyed this first episode. It felt very cinematic. The score was brilliant, and I quite enjoyed hearing the FC theme, especially during the end credit. Or is that the new intro for the following episodes. It had some amazing little details on the LCARS screen.
Now, I will say some stuff bugged me. If Lower Decks is canon (a word I absolutely hate), why was the Titan-A Riker's old command? We can ofcourse say that he took command of the Titan-A after the original Titan. But it felt a bit weird.
Shaw being an asshole enough that he basically orders Seven to accept her human name? That is literally not what is allowed in Starfleet. I know we've seen captains who have been more rigid, like Jellico insisting that as a ranked officer Deanna had to wear a uniform. I can see that. But for Shaw to be like that..... One message from Seven to an admiral would have had Shaw get a reprimand. Perhaps real life military is like that, but the fictional one that was created for this universe works differently, and individual rights are more observed. That was some really bad writing.
When the recruitment bureau went, I was pretty impressed with the shot, but we saw it in the trailer. Seeing it being dumped out of the sky onto the city..... Holy shit. Jawdrop moment.
The amount of little easter eggs through out the episode were perhaps a bit too much. I enjoyed them, but still.....
Other than those things, I had a great time with this episode. I'm not going to base any judgement yet, because this was all still set up and introduction of plot and new characters. But I was happy.
