ELI5: Why are people swayed more by negative reviews than positive ones?

When searching for things on Amazon, there can be 100 5-star reviews and and one 2-star review, and for some reason I give the 2-star review more weight in my mind even though the overwhelming consensus is that the product is great.

It's the same with film reviews. I'll find myself hesitating to watch a movie because of a single bad review despite there being universal acclaim from every other reviewer.

You're more worried about what could go wrong than what can go right. Same reason you fail to notice something in the background of no importance but your brain instantly alerts you of a perceived threat in your periphery (like noticing a giant spider in the corner of a room). Your brain alerts you more of the things that can affect you negatively and focuses on them more than positive things to keep you safe.
