As always, the tenth season had a great many memorable episodes, starting off with the follow-up to the bombing of NCIS in the series 9 finale, and several episodes dealing with the hunt for Bodnar. Hoeverm, seveeal of the DVDs have a flaw when you choose to watch the disc as a marathon; the second episode on at least discs 4 and and 5 plays as the last episode of the disc, so you get some events out of sequence, like Vance being shown back as director followed by an earlier episode in which he was just visiting. I verified that on disc 5, "Seek," the 18th episode played as the last episode on the disc, after episode 21 "Chasing Ghosts." It is shown in the correct sequence on the episode selection menu. Disc 4 did exactly the same thing, with the second episode playing last. I am not sure why, but be aware of that flaw and go back to the selection menu each time to choose your episode, or some events will be out of order.
Regardless, this is a minor production flaw, and it is the episodes that are worth your money. I haven't checked the extras except for the few deleted scenes, which add some interesting bits. "Hit and Run," episode 13 is one such, showing the father of the dead woman coming to NCIS to thank the team for solving the crime. Deleted scenes are always a must-watch for me.
