Love: they're cheaper and have usually a clear focus in what they want to be and a clear audience they want to please. Less afraid of challenge the audience, and trying new things. Lots of them focusing on memorable gameplay, interesting narrative or both. More caring about taking advantage from the medium strengths and less aping (mediocre) modern Hollywood. I'm having lots of good FPS, graphic adventures, RPGs, survival horror games and more thanks to indie developers. In another words entire genres that dissappeared or have been dumbed down in triple A territory. Lots of my favourite games from the last 20 years are indies: Disco Elysium, Northern Journey, Withering Rooms, Return to the Obra Dinn, Darkwood, Ultrakill, Hotline Miami, Inside, Dreams in the Witch House, Amnesia, etc.
Hate/don't like: too many games about mental health or with the "everything is in your head" trope, specially horror games (ugh). Sometimes too obsessed on "homage"...and not even necessarily being successful on doing it. Too many poin' click games with no real challenge. There are many games, so there are lots of bad and mediocre games, and yes, veeery low effort products. Popular terms like boomer shooter. Overexploited subgenres despite having still unexplored territory...when a Tomb Raider spiritual successor, for example?
