I've been hearing the criticism that the bosses are over too fast, but I wonder if I had a different experience:

First 33% of the game: bosses take 15 seconds. I pretty much walk up and kill them.
Middle 33% of the game: bosses take 30 to 60 seconds. I can't just walk up, there's a trick to make them vulnerable first, and I'll have to do the whole process 2 or 3 times.
Last 33% of the game: bosses take 1.5 minutes or more. I can't just walk up, there's a trick to make them vulnerable, and I'll have to do the whole process 3 or more times.

Does that pretty much match up with everyone else?

I could understand the criticism, if literally ALL the bosses took 15 seconds each... but that just wasn't my experience in later parts of the game. But maybe I just wasn't playing correctly?
