Glassdoor 5 stars - does it even matter?

New here, please be kind :) I'm interviewing with a (very) fast growing tech startup in the bay area with an almost 5 star Glassdoor review (~500 total). I generally tend to just read the 1, 2 or 3 star reviews to see if there's a pattern, get a sense of what the unhappy have to say, because people are more likely to write about a bad experience than a great one (unless they're incentivized to or it has far exceeded their expectation and are genuinely really really happy with it, I may be wrong). Also if it's truly either really that bad, or really great, it would be a very detailed review and not just a one liner "This is the best company I've worked for" or "run for your life". I sorted the review for this company by lowest rating expecting to see a few 2 or 3 star reviews, and this company has a few 1 star reviews, many of which were very detailed (paragraphs) of how toxic the culture is, how there's no WLB, how the leadership/HR doesn't care about their employees, not hiring the right people, etc. Some went so far as mentioning people by name (I looked them up on LinkedIn and they're current employees). Some had someone from HR respond with generic "sorry for your experience, reach out directly for more feedback" type replies. I know one or a few people's opinions or experiences don't necessarily speak for the entire company and it depends on the team (one of the reasons I question whether any review anywhere, including Blind, is relevant when considering employment) but the 1 star reviews weren't just from one team and they made it seem like the company as a whole had a big culture problem. One or two reviewers commented about fake 5 star reviews (of course) so I tried to see if there were too many 5 star reviews in a short amount of time (only way I knew how to tell) and I didn't have to look too hard - there were about 10% of the total reviews, all 5 stars, all posted within a few days and they started right after a long 1 star review. I haven't seen such a pattern with other companies I applied for. Blind also has mostly positive reviews for this company so that doesn't help, this company seems great in all other aspects. I went from being excited and looking forward to the next round of my interview to feeling like maybe I should withdraw (unless there's such a thing as fake 1 star reviews written with great detail, who would go to that trouble?). Assuming you don't know anyone who works at the company you can ask, how do you really get a sense of what a company you're considering joining (considering all goes well) is going to be like? Especially if a positive culture and collaborative atmosphere is most important to you? Getting a lot of 1 star reviews for the same issues is a bad sign, but does that mean the lack of 1 star reviews is a good sign? Have you joined a company with great company reviews on Glassdoor or other sites, only to learn that it was a toxic work environment and culture that you had to leave? For those that may think "it depends on what you mean by toxic, it could just be an issue of culture fit", what I mean by toxic is - lack of respect within your team (or in the company in general), not being heard (your opinion never matters), leadership that publicly criticizes and does not care about your professional development or your wellbeing, negativity, openly badmouthing former or current colleagues (tolerating and encouraging gossip), unprofessionalism, fear based leadership (bordering bullying), fostering extreme competition, etc - that sort of thing.
