I think making a comparison that it looks akin to a SyFy movie of the week is stretching a bit. Even if you realize or rationalize that the teaser aspect is in play the comparison doesn't work. SyFy movies of the week are Sharktopus and such silly and bad f/x that to make that statement is just not genuine.
Let's recall how unimpressive the MOS teaser was in comparison to this. As far as teasers go this trailer delivers vs that. Let's see how the last and final TDW trailer looks cause your comparing this teaser to MOS 3rd and final 3min long one. Not really fair.
