To dig into this a little bit without major spoilers...
Loki's escape was interesting. The resulting events were amusing. I don't know about his sudden switch to "good" guy. Think about the reason he switched. Will events be changed if the timeline is supposed to work out a certain way? Regardless if he's there or not? I thought that was a bit weak.
I didn't see the episode as a sudden switch to a good guy. Even his 2017/2018 version, just before his demise in Infinity War, he was willing to sell out Thor and anyone else for his personal gain in Ragnarok. He wasn't nearly as bad as the "current" 2012 version of Loki. But even at his end, he wasn't a "good" person.
I think him seeing the items he has been chasing for years, thinking they were the most powerful things in the universe, are paperweights at the TVA made him realize their power. He decides to go with the TVA request for now. His long game is to eventually use the TVA's power to change the future timeline he's now viewed. He always wants to be a ruler over everything. I don't see his goals to correct things in the future for the betterment of others. As he now knows in his purpose in the universe. He will try to use the TVA power to make his dreams of ruling all a reality. Sure, he may grow more of a conscious, but he won't let it get in his way most of the time. At least that is my guess early on.
I enjoyed the first episode and look forward to seeing the rest of the season.
Seems a bit sloppy to me to have infinity stones as paperweights. I get the point they are making but what if a TVA employee has a stone in their pocket and leaves the building and dampening field? Wouldn't they be torn apart like GOTG? I'd think the stones should at least be locked up so they don't get out like the Wuhan virus?
