These guys are ultra-nepo-babies and this album is basically funded with Epstein money. But you really can't overstate how much better this album was than basically ALL mainstream rock at that time.
Personally, I have a hard time evaluating Is This It because it was so meaningful for me around ages 14-16; and also, I had pretty much disavowed the Strokes by the time I got to college. It's important to remember that in 2001, when this came out, the available rock music on radio/MTV was either nu metal or pop punk with practically zero deviation. The Strokes felt cool and different and even "hip" in a way my friends and I couldn't put words to. The songwriting is really unique, and (despite the fact that they're pretty much churning out eighth notes 99% of the time) the band kinda cooks. I definitely remember learning about Television after reading a music mag that (favorably) compared the Strokes to them. Julian's blase too-cool-for-school thing can be irritating, but he can also belt like a soul singer when he wants. Nevertheless, the "coolness" can be kind of maddening, especially because these guys weren't particularly "underground" in any of the ways they fashioned themselves.
Overall, there's about 10 billion reasons I could dismiss this album, but I still like it and it scratches an itch.
