I would say that it isn't to the point of standard DVD, yet.
I think I was surprised when I first got into Blu that a lot of Blu-ray discs are poorly authored, with not only authoring errors but a lack of menus. For example, with TV series discs you usually expect a menu to let you select individual episodes, but I've watched at least 4 sets now from Warner Brothers with NO menus. To get from episode to episode, you had to scan through each episode. This is pretty rediculous and retrograde really. I've also had at least 2 motion pictures without menus. It seems the "trend" for Blu-ray movies is for the movie to start without any menus, and the menu to be a pop-up. Add to this that BD discs are worthless unless the transfer is HD quality. At least one of the discs I've viewed recently has been no better than the standard DVD version.
With BD discs, we also have AACS copy protection as well as BD+. Fox and MGM are using BD+ as well as AACS. These keep changing as time goes by. We are up to MKBv12 and MKBv13 for AACS as well as several revisions of BD+. What this means to you is that you will have to continually keep updating firmware on your standalone to keep being able to play the latest level of encryption.
There are lots of issues with standalone players not playing menus properly, or not being able to play BD+ titles, particuarly Quantum of Solace. BD players also have very slow load times compared to standard DVD players.
For computer based stuff, you have use something like AnyDVD if you don't have an HDCP compliant monitor to view BD titles. This requires an annoying subscription for updates because they are continually adding new keys for the latest titles.
On top of this, you may well have your internal keys on your BD drive revoked by inserting a "new" BD movie, because it updates each time you insert a disc. You can get to the point where your drive is "poisoned" and won't work anymore.
If you like fiddling with stuff, then Blu-Ray can be fun. It can also be annoying when stuff stops working or won't work due to poor authoring of discs or copy protection.
Just my take.
