Agree with everything, including that DL entertainment could use some more options. However, I am really, really glad that DL has bucked the trend and kept in seat screens that you can choose your own program on (looped videos?? C'mon UA, this is not 1995!).
Other US carriers are pushing the streaming option as the primary option. This has lots of drawbacks, and I really do appreciate that DL has nice screens where I don't have to worry about having working power or working internet (two things that very often DON'T work). That being said, I'd like to see some better film options.
