Loved the flow of the episodes, and there were some very funny moments throughout. There were some quirks with the way the characters acted, similar to the movies, but mainly only for Fry, Leela, and the Professor. Fry and Leela can be explained by the relationship overtones in the episode, and depending on how much they are going to play into it every episode, is not really a problem (they are still just as funny). If they play too much into it, then it could be annoying, but I doubt that they'll make this a romantic comedy all of the sudden.
The professor seemed to be missing too much of his senility

In the past, it was like 50% senile, 25% crazy, 25% disregard for his crew, which I don't feel has carried over in the same proportions. And when he does have senile moments, he seems aware and even proud of the fact that he can't remember things, where as before, he just seemed even more confused or completely indifferent (ex: "Yes, but what about the animals?!!" "the wha??? I didn't say anything about animals... Now, the planet is set to collapse in 3 days. Incidentally, this will kill all the animals")
But, as an absolutely diehard futurama fan who's seen every episode more times than I can count (including commentary), I'm still ridiculously optimistic following these episodes. Overall they were still amazing, and of a quality very similar to the average episode of past seasons. Looking forward to more.
