    Pontypool, great concept and execution for a low budget horror, Canadian zombies with a twist The Man from Earth low budget sci-fi about a guy who's been alive for thousands of years, mostly just character development and story telling through actually story telling. Deep Blue Sea 3, 1 was great b movie shark horror, 2 was garbage, but 3 knew it was on the back foot and just goes all in, not a great movie but after 2 definitely underrated.

    Deep Blue Sea 3 is a damn good DTV remakequel, with creative and quite gory kills and a pretty great cast. It feels a lot more comfortable being a shark movie than part 2. It’s all nice they’re skipping the dark underwater base for a floating fishing village instead. Give it a chance! #deepbluesea3

    Kelly is right. DEEP BLUE SEA 3 got the honored "movie of the summer" moniker from Fin Flicks. A truly unexpected treat after the lazy retread in 2. Here's @travisnewton.bsky.social and I giving it much deserved love on @genrevision.com. genrevision.com/posts/deep-b...

    #NowWatching Deep Blue Sea 3 (2020 John Pogue) Skipped right over 2 cause I heard it was a bad remake of the first movie. Hear this one is pretty alright though! #sharktember

    Deep Blue Sea 3 isn't a great film but it has two kills that made me sit up and cheer out loud. Sometimes that's all I want from a horror movie. So I just want to throw some appreciation at what is probably a very overlooked (understandably) sequel.

    This is probably my least favorite out of the series. Way to much of a storyline. Their still hunting down the bull sharks from part 2. The only part I like is when the ex of the star actor says this heroic speech and tries to dive in the water to go be with her, but except he dives right into a sharks mouth lol.

    Not as great as the original movie, which is considered the second-best shark movie since Jaws (1975), Deep Blue Sea 3 still manages to keep you entertained with better CGI, a better plot than the second instalment, and an overall active screenplay that is more about 'sharks on a vengeful killing spree' than 'humans making dumb decisions'. Watch it if you are a shark film aficionado like me. (Grade C). TN.

As she and team go about their routine, a boat arrives with her ex and a team of divers. The new arrivals…

    Better than the lame sequel and this one does have its moments, including the shark killing a character following a valiant speech, but many of the characters were, especially early on, a bit obnoxious being the cliched preachy environmentalist. In addition, performances weren't exactly the best either. However, there were some fun kills at least so it's probably worthy of a rental, though still a far cry from the first film. 2.5/5
