Honestly i'm probably not that target, however quite a bit of what you said does apply to me.
I was in to Pokemon from the start here in the UK, I got Pokemon Red and never looked back. Gold / Silver were amazing, I imported them from the US months before we get them though a shop in my hometown. I've been in and out of Pokemon since. I got back in to Diamond on the DS at University with some course mates, then went back and finished Ruby and Leafe Green on the GBA. In recent years the X / Y on the 3DS got me hardcore back in to the series, I then went back and finished White and Black 2 and have kept up with the franchise since, including Lets Go on the Switch.
In some ways I’m kinda lucky as I’ve enjoyed Pokemon Go since day one and still enjoy it today. I also love the core games too, so at present is a great time to be in to Pokemon, even more so as I’ve met new people in my home town also in to the franchise though Pokemon Go.
The movie in general just look a bit rubbish to me, however I’m not all that bothered to be honest. I’ve always been in to the games over the anime so I’m good either way, I just never expected the movie to be as hyped as it is!
