To respond to that effectively, I would need to know everything you've noticed.
That'll probably have to wait for my review, which will get written this month if I'm lucky.
I don't require the unconventional, and this certainly isn't.
I like for Switchfoot to try a few things each record that are unconventional, at least for them, and I think they've done it on every record, with varying levels of success. But yeah, this isn't experimental, challenging, indie music. It's quirky pop/rock, which is what they've always done best. Just a teeny bit more on the pop side. I would say that's what I like a little less about it, but TBL is their poppiest album and it is my favorite, so I don't know.
It seems authentic to me, and I had fun with it. At the very least, nothing strikes me as vastly inferior to their other work I like.
I wouldn't characterize it as "vastly inferior" either. I probably expected more, so hearing a result that didn't throw as much of a curveball as I'd have liked might be the thing that's bugging me. It feels like a standard Switchfoot album to my ears. It's their first album as an independent band. I expected it to make more of a statement. (I feel that way about Jars of Clay's latest, too, though that one's grown on me over time.)
You might note, though, that I did rate it in the B column, which is basically where my favorite albums from this band so far have ended up (and where the best vanilla has to offer usually ends up as well).
I have it at a B minus. We're coming out in roughly the same place; you probably just came in with more reasonable expectations.
