These photos in the link to me seem fine and made me wonder if the photos in the OP were maybe taken by an assistant? Those almost looked like images that didn't turn out well that would be omitted and not sent to a client. I wonder if you got sent some of the wrong pictures by mistake.
I tend to agree. Rather than photos of inanimate objects, I would have liked to see some of the pictures of the bride/groom/family to see if they were on par with the portfolio. Picking a few of the worst to compare to the photographer's best (i.e., his advertised portfolio) isn't a fair comparison.
When the wife and I got our wedding photos back, the photographer said she'd give us all the photos from the night. While I'm assuming she culled some of the worst ones, including "all the photos" is just inane. So many repeats and boring photos, not to mention photos that would NEVER make it to a portfolio for her website. When I look back at the photos, I like the pictures of us and family. I don't care about the flowers or the table settings.
The pricing to me did seem low, in my area it's more like $2-3000. Your location shows NY so I'd expect that to be quite low there (for NYC that is, not necessarily in other parts of the state). I don't know, there are a lot of people with cameras listing themselves on social media and it's probably better to look further than that and see if they have a website or set up at any wedding trade shows, etc.
For what it's worth, when the wife and I got married nearly a decade ago in NYC, we paid over $5,000.
