I'm definitely still watching, but as someone who puts that particular joke in my own Futurama top ten, I'm amazed that you're not having the same reaction to these new episodes. The show isn't nearly as intelligent as it was. Maybe it never will be.
My reaction is one of Futurama is back, as that is I am willing to hold fire on an opinion until we get about four or five shows in. That to be honest is how long it took the first series to start hitting its stride. Okay you can say that the guys have had five series and four FL episodes to fall back on but we also have to remember that those five series as ended up with the show being cancelled. The show was going to change and I think it will take at least a seasons for them to find out what angle to take the new episodes.
If the show does feel the need to make constant reference to pop culture and making pointless jokes to non story specific events then yeah that will get tiring, after all we already have a show that does that and that's called Family Guy. The opportunity is there and I can sense that the basics are there, despite what some say the second episode, bar maybe the ending felt like old Futurama and the start of the third felt old school Futurama until it speared off on the Iphone hammering.
