They purposefully made the starters shit to shill Greninja. The sooner you accept it, the less shit you'll get.
So please stop shitting on each other's opinions. Your favorite starter is the best, and some people will agree, some people won't. Doesn't mean you should impose your opinions on them.
So just accept it. You will always carry a bond with your favorite pokemon, and that's infinitely better than some overrated edgy shillmon that gamefreak releases.
Have a great day, and have a great, long life!
