Well done to Eon's marketing strategists - they've got exactly what they wished for. But it's surely not controversial to suggests that while a chart number one is certainly a stamp of financial success it is by no means stamp of critical approval.
I wouldn't think it would be controversial to say that, but I'm sure someone will try to make it into a controversy.
The sad thing is that financial and critical success aren't mutually exclusive things. There's no reason that EON/Sony couldn't have hired an artist that could have managed to turn in an effort that could have garnered both forms of success. Instead, the quicker and easier path (quite literally, since only 20 minutes of time was put into this song) was taken rather than searching for more accomplished, yet still popular, artists to take on the task and, perhaps, maybe even put in a full half hour of work into the project.
