This was a fascinating & superior updating of the 1966 Irwin Allen series of the same name.Unlike that(and all of Allen's sf series)show, this is an intriguing & well thought-out premise.While attempting to create a clean,renewable,& abundant energy source,the Dept.of Energy inadvertently rips open a time vortex into past ages.A timestorm then ripples throughout these distant eras which in turn causes anomalies that disrupt our present.The TT complex is shielded from these alterations & realize how history has changed.They have plotted 240 anomalies which need to dealt with,so a team of experts are assembled in order to journey back in time in order to correct the errors caused by the anomalies,& then are retrieved back to the present.This would have been a wonderful series had it been picked up.In its premise it answers the problem inherent in all time travel scenarios:the past cannot be meddled with,no matter how benevolent the intentions are,because it may produce harmful ramifications all the way into the present.But here the time-team must restore the past to what we know it should be,their missions are to make things right.While this premise is hardly original & has been used by other TV series such as Voyagers & Quantum Leap,it works.The cast was likable & you cared about them.The fx were terrific.What a shame we won't be watching them return to the past to set things right with those other pesky 239 anomalies that are left.
