tl;dr Motivate me to play Gen 5

So when Black and White first came out I was an underage whiny snob who at first was into it, but after time I couldn't dig it anymore. If memory serves me right of why I disliked it, the graphics gave me a headache, I didn't like how a lot of the new Pokemon seemed to be carbon copies of old ones, the routes trudged on for a while, I thought a lot of the features proved the beginning of casualization, and I found the story to be too try hard. I ended up quitting it right after the 8th boss, and never finished it. Basically lost all my interest in the series for a bit. Didn't even realize B2W2 came out, bought XY two months late, and then my extreme interest in Pokemon returned from there.

I've been broke for a while but recently my younger brother lost any interest in keeping his copy of White (I played Black) and I realized I really should finish every title at least once to claim I'm as big as a fan as I do. I've heard B2W2 is a better game but also that it's a direct enough sequel that you'll be lost storywise without beating the first one. So I'm gonna see if he'll give his up but I'm still not 100% excited to be beating a game I dreaded so much in the past.

So /vp/, tell me your favorite things about Gen V, and convince me it's worth it to play through this game and then eventually B2W2. Also, let me know if I should go with B2 or W2, unfortunately don't have a choice for the first game
