As an artist, the take that "modern art sucks" isn't controversial, though most people don't actually understand what modern art is. Modern art is art that's from 1860s to the 1970s, including any artist works that favored experimentation and expressionism.
So do you like starry night? Congrats, you like modern art. at least, you like one type from that catagory.
if you mean the blank color blob art:
this is Abstract Expressionism. A lot of people don't like it, but then again it's extremely hard to appreciate it in photos. It looks really stupid online but when you look at in person, you realize these are huge. You're supposed to sit in front of it and immerse yourself in the color, and let your mind wander.
Like, sure, it's not as narrative as say a biblical painting of the virgin mary or something, but its still art IMO. It's just not everyone's vibe.
