Megadolon is more a mediocre movie than a terrible one. It is also at least better than the Shark Attack movies(then again almost anything is), now those are examples of terrible movies. There are things to like, the acting is decent especially from Mark Sheppard, there are some nice underwater sequences, there is one cool attack scene and much of the CGI is not bad(the helicopter crash agreed was an exception), not great but could have been worse. Also the movie doesn't fall into the dull category, the pace is quite brisk and there are glimpses of great entertainment. Megadolon is let down by a number of things. The standard of the CGI was better than expected, but there could have been much less of it at the same time. The editing has times where it's hurried and others where it's sloppy, the dialogue at best is a load of exposition and cornball and the characters are shallow and development is next to nil. The story is not badly paced, but it is very predictable and the suspense and horror is severely lacking(they're exchanged with unintentional comedy, some of which is funny but others are frustrating), and the repetitive attack scenes and anticlimactic and quite ridiculous ending hinder it further. The shark is a very mixed bag design wise, there are times where it has a very menacing great white shark look but there are other times where it is like an over-sized plastic toy you'd find in the bathroom(coming from someone who used to have one, it could sing too!). The lack of personality is a big problem, there was definitely a big effort to make it authentic but generally it needed to be more fearsome and have more variety in movement and how it reacted to things. Overall, mediocre but did have its merits. 4/10 Bethany Cox
