a lot of sci fi this year is a relative term. lost ends this season, so abc needs to find a replacement desperately. two new shows just before lost ends could be considered almost too late. Flashforward is getting mixed reviews and probably not huge ratings or they would be hyping new episodes more. V had a ton of production issues before it even aired(they are on their 3rd show runner now).
They burned thru 3 episodes of plot in last nights pilot. Too much happened, too many people were making big decisions with little setup to give weight to those choices, too many important secrets were revealed, and the biggest twists were shot right out at the end of the first hour.
Blame the network, as apparently they rushed production to get it out before american idol and the olympics start up.
The original series had the advantage of no one knowing what the visitors were actually up to from week to week, and no interwebz filled with spoilers. Discovering the V's were sinister, and then finding out they were reptiles took weeks in the original. Right now all the new team can do is go for style and try to have better acting than the original.
