Is the second and third worth a shot ? I finished the first about 2months ago and it was absolutely brilliant.
Having seen only 1 film for each of BTTF and Indiana Jones franchise, I think the 1st BTTF dated much better than Raiders of The Lost Ark
t:, yes, absolutely, they are worth seeing, but each film is very different to each other in style & approach. One of the most complete trilogies ever made.As a kid Part II was actually my favourite for a while.
What I love about the trilogy is that it covers everything you can do with time travel in this contained environment: present, past, an even further past, future and alternate reality. It checks all the boxes. They don't pull the same trick twice, each sequel had something different.
Revisiting the first movie from a different angle is just genius. The first one will always be the best, but as sequels go (and we know how bad sequels can be), what they did with both parts is kind of amazing. They managed to use time travel wisely without losing what made the first one so special. I think as a trilogy is perfect.

lol, I dont understand why people have a problem with 2&3? The entire trilogy is amazing. I love them all. When I was younger, 2 was my favorite, The I got older, and I was a hard 1, but 3 has been growing on me a LOT.
Just a great trilogy. You cant go wrong with any of them.
