We have a time machine! We can go anywhere at any time!
Let's go to a concert that happened 3 weeks ago. /credits.
shareOy, pay attention to the bloody film. They couldn't go just anywhere. They had a very limited reach based on the power source. They could only go back a month or a few months. So they had to go to that concert, they couldn't have gone and seen The Beatles or Mozart or Robert Johnson. The only time they had a wider reach was at the end when he went back something like 10 or 15 years when he had the extra powersource from the school. At that point obviously he had bigger issues to tackle but even if they were looking for a concert to go to, heck he wouldn't have even been able to see Nirvana.
