Well, based on the overall perception that I've been seeing in the run-up to release, people have been trashing this game to hell and high water. Not really sure why, but common complaints were the GO-style of catching and the fact it was Kanto again. If you don't like the game, the chances are that it's not for you (the overall audience of this is GO players, young chaps and (to a lesser extent) people who started with RBY or FRLG), but considering how vocal the haters are, it's really hard to see a positive opinion about this game.
Then I picked up my copy of Let's Go Eevee, plopped it into my Switch, and started playing it, expecting the game to be an absolute calamity. Turns out that it actually felt like a real Pokemon game, except with GO mechanics and the frustration of wasting several Pokeballs on a Pokemon. While people bash the opening act for being too easy, it was most likely done not to scare off the target audience and ensure they know how to build a team instead of just relying on their strongest "CP" mon. Even with the difficulty backpedalling for that part, I noticed that levels started to spike around the SS Anne, and they kept going at it relentlessly, so it's not all "too easy" (despite the EXP Share being added in that can't be turned off) but rather a good balance. Some of the Coach Trainers (I'm looking at YOU, Route 7!) gave me a bit of trouble as well.
All in all, it's actually quite a fun game. I even got a bit nostalgic at some parts, harking back to when I first played FireRed as a kid.
