Personally 5>1>3>2>42/5 episodes being better than average Rick and Morty and one about average is a good run, although also getting the new worst episode is kinda eh. Plus I don't think any have been truly excellent yet. So basically a good set of 5 episodes but they can do better and hopefully the next 5 are. My ratings, if 0 is worst Rick and Morty and 10 in best:
I think if episode 1 had better pacing I'd think more fondly of it. It was great. But pacing is pretty important.
ep 1: 7/10
ep 2: 4/10
ep 3: 5/10
ep 4: 0/10
ep 5: 8/10
