Sharktopus (2010)

An intentionally silly film in the Sharknado vein, but from a different production company, this has scientists creating a part shark/ part octopus creature with a radio control that makes it a weapon the military can control. Of course, the control is lost and the creature goes on a rampage. Eric Roberts stars among a cast of mostly wooden non-actors. There's absolutely nothing remarkable about this, except that it's pretty watchable. So far, there are two sequels: "Sharktopus vs Pteracuda" and "Sharktopus vs Whalewolf," with another, "Sharktopus vs Mermantula" in production.
