After 04's generally underwhelming Futures album, it seemed like the emo-kids-turned-adult-alt-rockers were at a crossroads of sorts, unsure if moving further away from their solid, albeit predictable formula was the right way to go. Light is both a safer extension of Futures and a polished and refined redux of earlier work.
The mostly uptempo pop songs are still undeniably catchy, full of that eager desire to tug at the heartstrings. That's what makes them enjoyable, even if it's at the expense of trying new things.
Call it what you will (post-pop punk?), the fact is that Jimmy Eat World know how to please their fans with memorable hooks and intelligent writing. Not amazing, but steady and fun all the same.
