Pretty good premiere. This was probably my most anticipated return for any of the shows that I watch and it didn't disappoint. Was really curious how it would play out. I knew that they would drive home the fact that Barry was finally happy now that he had both parents to lean on.The events pick up 3 months from the end of the Season 2 Finale and everything is all roses for him. The interesting thing was that the more Barry uses his speed power, the faster his memories start to fade from his previous timeline. Naturally this means he would eventually have to reset the events as it was before which is what the episode ends on. The epilogue is that everything is not the same which is a great way to kick off the rest of the season. Where did he go wrong and how does he fix this without doing even more damage? I was surprise that they reversed course so quickly. I was expecting at least half the season to be devoted to Barry's alternate reality. It was fun to see how everyone else's life had changed in the alternate reality. Too bad we can't get more of that.
