Two things to watch -- the number of reviewers AND if the review is for the correct year, or is it an aggregate across years?
I don't consider wines with less then 50 reviewers, unless I have another reason to buy it. I prefer more than 100 reviewers, and while I might rate a wine a point or two under the rating, I've had good luck. [I spotted a Syrah rated at 5/5! WOW!! Except it was only 1 review ....]
I had VERY bad luck when I didn't realize a rating was an aggregate across years. The wine was rated 4.1 at a very good price, so I bought it. Popped the cork, and it was too young. Very green. It had potential ... in a year or two. I looked at Vivinio again and spotted that the rating was across a 10 year span. The vintages of 3 years and older were well rated. The last 2 vintages were not.
When you buy a wine on wine critic reviews, look it up on Vivinio. If you can make it work for you, it's really handy for off-the-cuff purchases.
When I was little I'd get a sip of whatever my dad had, either beer, gin & Wink (grapefruit soda), or gin, sloe gin, and orange soda. By the time I was 14 or 15 it was acceptable to have 1 beer, which was sipped, not chugged. When we got done with hunting, we'd get back in the car (rifles unloaded and in the trunk), and my dad had a small flask of wine, and we each had a healthy slug. He's gone, but the memories persist.
I'm not doing it wrong, and I have definitely moved on from Vivino. Now, you give me a bottle well-reviewed by those trained in Robert Parker's legacy, or by James Suckling, a more than 92-pointer from one or both of them that lies in my regional, varietal and/or blend areas of interest, and that's almost positive to be a sure success on my tongue. (On the other hand, I dismiss out of hand any Tasting Panel reviews, for example.)
That said, the most surprisingly delightful overall commercial wine I discovered in 2022 was Southern Belle, a jammy, open and aromatic Spanish red blend with quite a bit of Tempranillo that was the very first to be aged in used whiskey barrels – Pappy van Winkle barrels, to be precise. It's also modestly priced at around $18-22 a bottle (unless you want to pay more, and then you can). I bought a glass on a lark at a restaurant, and now there's most of a case left in my cellar. It coincidentally does rate 4 on Vivino, I just found out by peeking.
While I am peeking in the other window, the best wine I tasted in '22 was 2018 Long Shadows Pedestal Merlot, which is highly rated by those I respect and a 4.2 at Vivino (I'd rank it 4.6). For around $70 a bottle, though, it OUGHT to be good. Yet that is not always the case.
And I also drank Perrin Donns Pitch Black cab ($11-15), a 3.8 on Vivino, that was very subpar. I'd give it 2 stars or less. But then the $10 and 3.5-Vivino-rated Excelsior to me is a near 4-star wine above its $10 weight. That was another lark, served at a reception dinner, and case of it is in the cellar.
The ~ $15 Chateau Mayne Vieil Fronsac that's a staple in my cellar only rates 3.6 on Vivino, and yet every time I take a bottle to a party, people are snapping photos of it and asking me where I got it.
My Vivino results back when I used it were highly uneven. I do better listening to actual experts who have similar wine views. And I try to rule out price as an indicator of quality anymore. I find it's more fun for me to find a $10-25 bottle that is an eye-opener than a $50 bottle that tastes like it should at that price.
