poor old sean astin . hot off the success of lotr he end up do this dull excuse for an action sci fi movie . slipstream be dull . not boring and just dull . i have hop for more seeing a how vinnie jones be in it . but he be horribly hamstring by not be able to swear properly . substitution for the f word such a flame just aren not funny when they come out of his mouth . remind me all to much of a network version of alien i saw some year ago and where hudson keep say frickin a. in a completely different voice than bill paxton . at least here they get vinnie to do the word . but it still sound just wrong . because of this and vinnie isn not remotely funny in this film . sean seem terribly ill at ease and the rest of the cast do nothing spectacular . in short and the movie be just dull . i do not mind the silly physic of time travel and but i do dislike lack of common sense when movie be make . here and we be tell that the time travel window to the past be just ten minute long something to do and we find out later and with not have enough power . but dear old sam sorry and sean have no problem use his device several time over in those ten minute and effectively go back over the same ten minute again and again . so it beg the question . if you can use the device repeatedly and why not go back 10 minute and then another 10 minute . and so on . all in all and poorly think out and badly execute . let hope this film drop into obscurity and do no harm either to astin or jones career .
