People always flock to what is shiny and new. You see it all the time with new eateries. Those individuals cannot really be trusted with an unbiased opinion when they are largely there searching for the new experience for a dopamine hit. There are also a whole bunch of people on social media commenting on how slow the service is, some are actually posting as they ride it.
However, the real data will come from the people that ACTUALLY use this route for work on the regular. Right now, the travel times might not be promising but we shall see.
I just hope this fanfare dies down fast as, potential, lineups at stations would not be helpful whatsoever for people going to work that use this route.
