I loved this Movie for years. I just watched it again and was so confused. During the time where the loop closes they are still in 1943 but i thought the loop was gone. How are they still in 1943???? And wouldn’t the bomb kill them? Also during the time where he goes back to see his grandpa makes no sense. If killing the bad guys makes the grandpa still be alive, he wouldn’t have met the children so as soon as they switch time lines they would forget who he was. Also he said he joined the military and spent 2 months in France???? His dad just forgot about him? FOR OVER 2 MONTHS???? Anyways the acting was great in my opinion and I love the story. Samuel L. Jackson was a great addition to the cast. Overall 7/10
