SP (2007)

SP much like BG has intense action scenes and features some neat hand to hand combat.

There's a small connection in the sense that the protagonist of BG is a former SP, whereas SP is obviously about the SP themselves.

more/less the show have similar premise, the difference is that BG features an ex-SP and a bit darker than SP.

Both dramas are about a security team that combats the day to day occurences that threaten innocent citizens.

Both were written and directed by the same people. These two drama both have protagonists that are very observant and are in the police force. SP is more focused on action instead of mystery, since you know who the bad guys are in SP right away, though there is some mystery. They also are both crime and thriller dramas.

Both dramas has similar plot, such as protecting important people. Both dramas have great action scenes too.
