I bought Star Trek on Blu-Ray today and it was totally worth the purchase. The bonus content has a lot of featuretes about how the movie was made, hilarious bloopers, deleted/extended scenes, which were good to watch as the movie (guess they took 'em out for time) and a ship navigation feature exclusively on Blu-Ray. You can freely explore the bridge and halls of the Enterprise.
As for the movie itself; Not only do I think this is the best Star Trek movie (with all due respect to Wrath of Khan), but it's one of the best Sci-Fi movies out there along with Star Wars, Blade Runner and Alien. The visual effects, the gripping chemistry of the crew, the enticing plot made it as great as Star Trek once was back in the '60s. With the crisp picture, astounding colours and it's booming audio of Blu-Ray, it really made this breathtaking experience as good as when I saw it on the big screen last May.
