Slasher is not my favorite subgenre, but some of the modern ones that I liked:

All the Boys Love Mandy Lane (already mentioned)
Behind the Mask (already mentioned) - although I didn't really love the "slasher" parts that much, but the meta stuff was good

Alyce Kills
The Children
Cold Prey
Dream Home
Halloween remake series
Hatchet series
Inside
Macabre
Midnight Meat Train
My Bloody Valentine remake
Toolbox Murders
Texas Chainsaw Massacre remake series (not low budget though)
Wolf Creek

I'm using a fairly strict definition of slasher, but not quite as strict as Vera Dika. Basically, I typically require that

a) the killer is usually a single iconic type character (beyond just a psychotic regular person, like, say American Psycho) - probably masked, deformed, or somehow "different"

b) the film isn't typically about the killer (like Henry: Portrait), but rather it's about the victims

c) the victims get picked off one-by-one, so if there's only one or two deaths, I wouldn't call it a slasher

d) to some degree, the plot follows the slasher plot formula

I only mention this because there are a lot more films that I like that some might define as slasher, but I wouldn't, given that there might be a better subgenre to put it in. So, I'm not including films where a group of killers terrorizes people (The Hills Have Eyes... I broke the rule for The Children because the plot is very slasher), or captured and tortured (Saw), home invasion (You're Next), demon possessed (Evil Dead remake), or films about the killer (Found, Killers, Maniac). I like all those additional films I just mentioned though, and some would call them slashers.
