This is one of those times where I wish IMDb allowed us to comment on each other's reviews. I'm really at a loss as to why this is rated so highly. Special effects were great but beyond that it felt like a really long trailer, and a slow one at that. We learned nothing about any characters, and with the alien's telepathy it seems like they would have wiped out humans in a matter of days. There was no discernible plot and it went nowhere. Both my wife and I couldn't believe how long this made the 20 minutes feel. Maybe I'm missing something...
