The IFE offering has been stale for quite some time. On a recent segment across the Pacific, I realized that the same episodes of Hawaii 5-O and a few other shows were being shown for at least three months continuously.
The selection of TV and movies is limited to begin with, but some of the entertainment offerings could benefit from a broader choice of stuff to see. The music channels are decent, I'll give you that.
The best selection of IFE on a US-based carrier has to be Virgin America.
