It's complicated. Season 2 corrected some mistakes of S1, Pike was the biggest positive thing in S2, and I think people liked and anticipated that they will show Enterprise bridge. S2 had way less violence than S1, and CGI is much better. On the other side, writing is still pretty weak and while they did have a few great episodes, the rest of the episodes stand way lower than those good ones. For example, good ones are 6, 7, 8 and the rest is 2, 3, 4. Biggest problem is that writers don't know what they want to do with Discovery. There is very little of exploration, very little of space anomalys, very little of technical stuff about the ship. Those are the things that people liked in previous Treks.
