Ah, now eventually you do plan to have megalodons, in your megalodon movie, right?
For a movie featuring giant sharks, there is an awful lot of tangential story development and action that features big sharks only in the background. At least Spielberg had a reason the shark was not seen much in the opening act of Jaws. Director Ben Wheatley seems to think this is an espionage, action thriller and that the sharks are not really why we are coming to see this movie. The movie starts with a James Bond of the Oceans sequence, then spends a big amount of time playing Armageddon games. Then the movie transitions to Die Hard on the high seas, before turning into Jurassic Park of Thailand. Finally we get to the good stuff, and what do we have? Mega Shark Versus Giant Octopus.
Look, this was always going to be a popcorn picture that we laughed at a little, but still felt like it should be taken seriously. That does not happen. There is nothing you can take seriously in this movie. When we start meeting the new characters, the first one is basically working on his Iron Man suit. The villains you can pick out in a few seconds of screen time and the set up for the climax moment is presented as if the character who will use it did it as an afterthought.
I like Jason Statham films a lot, but there are getting to be too many "Fast and Furious" imitators out there and if he is going to be in all of them, he will be overstaying his welcome. He is great in the action scene opening, and he does a great impression of Ed Harris without the liquified oxygen. When we get to the actual shark battles that come at the end, he looks good enough on a jet ski, but the cars and motorcycles of the other series probably make this feel like a repeat. So many of the shots have a deliberately cartoon feel to them that there is no suspense at all. I understand the presence of sub-titles since the film is partially produced by Chinese interests and will be marketed there, but some of the Chinese style shorthand in storytelling, makes the film even more like a Syfy weekend programmer, in spite of it's budget.
Shortcuts are taken everywhere. How did the most technologically advanced company in the world not know that part of it's resources were being given steroids, so that an even more advanced technology can make the impossible, possible? The cash and resources can't be covered up like a bookkeeping mistake. The usurping of the chain of command is also something that just does not get explained. Maybe Chinese audiences expect that from capitalists, I don't know or understand. The secondary heavy, a bad French sailor, is smart enough to know that a boat engine will draw a meg to a boat when he is warning his troops, but twenty minutes later, he is clueless and we know bad stuff is going to happen to him. 
After we have escaped Blofeld's drilling platform, oops, I mean Jing Wu's scientific sea station, we relocate to an area that will give the audience the surrogate thrills they are seeking, but it pays off a lot less interesting than the first fill. Even with Megmouth Cam. To punch it up, other characters have to become action heroes, and against all odds they do. Of course it requires the bad guys to ignore the common threat to everyone on "Fun Island". Yes, it is actually called "Fun Island". It's been five years since the last film, and that interval resulted in the laziest writing you are going to get in this summer's film lineup.
"The Meg" was so much fun, you just assumed that a sequel would have it's moments. No, it doesn't. it's like a beached shark instead of a beached whale. The crowds will stand around it for a little while, but after a few days, the smell will drive them away.
