'River Monsters' Premiere: The Search For A Bull Shark; Exciting Or Too Slow? (VIDEO)

Jeremy Wade and "River Monsters" (Sun., 9 p.m. ET on Animal Planet) returned for a fourth season, with Wade on the hunt for a bigger and better monster. He came up slightly short with a juvenile freshwater bull shark, though it was still six feet in length. Ironically, while looking for the bull shark, Wade found a seven foot long, 350 pound grouper.

A grouper might not traditionally be thought of as dangerous or a monster, per se, but when dealing with that size, it certainly seems pretty monstrous. The TCPalm says the show is a "fun reminder that we have some special creatures sharing our environment with us."

The New York Daily News, on the other hand, was a little disappointed with this premiere. They feel that the series needs to talk less about the monsters sharing the world with us, and spend more time showing them.

See the show wrestle with the balance as "River Monsters" continues Sundays at 9 p.m. ET on Animal Planet.
