I'm sure that it's awesome.
[UPDATE] It seems that the trailer was pulled from YouTube. Though it also seems that Eurogamer still has it. And a search on YouTube gives you half-a-dozen more of them (once it's out there, you can never take it back) like the one I replaced the embedded one with.
Anyone's guess how long those remain. But either way don't worry; in a few hours they should all be available to everyone.
[UPDATE] Forgot to mention that the trailer apparently is originally from the Danish site Gamereactor. Here's the thread on the swtor forums discussing it. (Thanks to a reader for letting me know.)
[UPDATE] Get the full cinematic trailer (downloadable in HD quality) at the official website.
