This review contains NO SPOILER, because it doesn't give the slightest description of the plot.
In a popular way of saying, Silversun is a teenage fast-paced version of Lost. If you like Smallville, Blake Hosley High, Lost, Nip/Tuck, or any equally excellent show, you'll possibly love this show. I personally give Silversun a relative rating of 9.9, higher than all those shows mentioned.
Silversun the show has its own destiny. The show is broadcast at rarely watched timeslots on some less noticable(but actually great) channels. That only allows a small number of viewers who have real 21st century tastes to watch it. Only these elite viewers will be inspired.
The actors of this show, though did a superb job, won't be therefore assigned by big companies to do show after show, and that makes their roles unique and trustable, because you won't be watching this show and say "that guy is the same guy from XXX show".
Simply one truth: Silversun has everything but fame, which may just be the right thing for it. It proves to us that real talents don't always get discovered.
