There is nothing remotely original about " Bugs" but while its ingredients are familiar ones they are served with economy and speed which makes it a passable time -filler . When a new underground railtrack is built through the heart of a mountain there is a consequence undreamed off by the builders -the tunnellling awakens a horde of prehistoric giant insects akin to the scorpion .They are hungry -and no wonder for they have slept for millions of years .They attack a train and make a meal of the passengers The authorities send in a SWAT team and an expert entomologist ( who just happens to be a strikingly beautiful woman ) along with a FBI agent and a company expert to drive the rescue train . The team is attacked and its numbers depleted ,and it is left to the bug lady ,the agent and a few others to battle to safety while striving to kill the creatures and deal with the head of the rail project who is intent on covering up the whole business even if it means killing the survivors of the rescue party . The acting might politely be described as functional and the writing is basic but some adequate special effects and a brisk pace compensate and there is fun to be had spotting the references to other better known pictures as for example Alien ,Mimic and Jaws
Not bad at all
