Just want to be brief. This is one of the best Syfy has come up with in a while. The actors are great at delivering their lines, there's a lot of humor that just comes naturally to the characters. Everyone seems at ease with their respective roles.
Saw a few mistakes (I'm hyper-analytical), such as sound effects being added that weren't even there in the beginning of the story! I think sound effects pollute the use of superpowers in most films and shows--it's like using 555 for a phone number to announce, "Hey, we're in a movie!" Sometimes they're appropriate (laser beam eyes would make a crackling sound as the heat burns the surrounding atmosphere, for instance). Saw a couple issues with timing, such as ducking someone coming out of a doorway BEFORE being able to even see into said doorway let alone the person coming out of it. But as a whole the entire show out-shined those very minor flaws.
The characters are quite interesting, especially since some of their powers are quite underwhelming on their own (they're meant to be). Didn't notice any cheesy effects or typical green screen giveaways (I spot them most of the time, even in uber high budget films where the directors are gods in Movieland). Very little in this show requires the use of such special effects and the parts that do are executed quite well.
I lost interest in Alphas because it is too heavy-handed and doesn't bring anything new and, in fact, is over-the-top with a lot of stuff. While Three Inches has a very similar premise, the delivery is exceedingly better than Alphas as well as other shows.
If this isn't green-lighted for more episodes then I'm almost out of shows to watch on Syfy, save for Warehouse 13 (gets funnier every episode, which more than makes up for some ridiculous plots in some episodes, most of which include Fargo from Eureka--not his timeline, not his universe!) :)
