I think if I had played the original back in 2013, I would have appreciated this a lot more. Going straight from the original to new content makes it feel underwhelming, especially since the bucket stuff has you repeat a lot of areas from the original. Meta commentary is just not as impactful as it was when the original came out, it's been done, and done better at this point, which lessens the impact for me personally. This is especially true as the seems are so visible, and you can easily tell when a reset/new route has begun.
That being said, there were some parts that made me laugh out loud, which is rare for any game to pull off, at least intentionally. The narrator is really incredible, and is great at moving between a comedic and serious tone.
This game is definitely worth playing if you enjoyed the original, or are like me and have always been meaning to check it out but never gotten around to it. It's an important game even if it didn't resonate with me.
