Where to begin? There seems to be an unwritten rule that Disney Channel sitcoms must be mindless and badly-written. Yes, I know they are not intended for adults, but children are actually intelligent beings. As a kid I loved Wonder Years, which was an excellent show, very well-written. I also liked Boy Meets World, although even back then I could see that it was clearly worse than Wonder Years. Still, it was meant to be sillier and it had enough heart and integrity to make you care about the characters and be willing to accompany them as they grew up and learned life's lessons.
Now there comes this spin-off and I tried watching for nostalgia's sake, but I had to give up after forcing myself to watch a few chapters. Girl Meets World is bad even when compared to other Disney shows. It just has no redeeming features. Sure, it's nice to see Cory and Topanga again, but I still spent the time cringing instead of remembering fondly. They decided to make a spin-off of a beloved old show, and they took the trouble to hire the original actors... couldn't they have taken the trouble to hire decent writers too?
The writing is bad, and I would feel sorry for the actors for getting so little to work with if they did not do a bad job too, either overacting or being expressionless. Cory's classes are a mess, Farkle is a creep with no nuances, Lucas is inexpressive and vacant, Riley is all about making overacted faces, with no personality...
If you are interested in this because of Boy Meets World, sure, give it a try and form your own opinion, but be warned that you'll probably decide this is a painful waste of time.
