I think it's a good trailer. It sets up the central plot of the film, but doesn't really show you anything at all of the main focus (ie. the 1969 stuff) except the briefest of teases. Tommy Lee Jones does a great delivery of the line, "I promised you the secrets of the universe. Nothing more." And Josh Brolin looks absolutely fantastic. I do think the 1969 thing could be interesting; it gives them some neat ways to open up the MiB universe a bit and take the film in a different direction. Now, to the bad. I found the first MiB only sporadically amusing and the second was absolutely awful. Josh Brolin's genius aside, the absence of the real Tommy Lee Jones is not a good thing. I have always found Smith to be somewhat obnoxious and this trailer does not reassure me. "He smiles like this." *glowers fiercely* Wait, was that supposed to be funny? Final verdict? I doubt I'll be seeing it.
