I can understand people having a weak reaction to UnderTale if they've only seen reviews/promo material; the game is short and extremely dense, so there's not a lot you can explicitly talk about or show off without spoiling some seriously cool moments.
And while it may be really hard to recommend this game without being incredibly coy about it, make no mistake: EVERYONE SHOULD PLAY UNDERTALE. It's Really, REALLY Good.
Edit: Also, if you really can't just take people's word for it, play the demo, it's free on www.undertale.com, it's super short, has an INSANE amount of replay value for a demo, and unlike a lot of the more playthrough-style promo/review footage, doesn't have a dude loudly reading all the dialogue over the amazing soundtrack (I'm looking at you, Giant Bomb Quick Looks).
