I agree. I really dont know what the ST fans like about the ST to be honest.
Acting is ok but I do think a movie needs to have a good story to remain iconic and the ST just doesnt. Nor does it have any really memorable scenes worthy of a rewatch like Lord of the Rings or Avengers. You can see they try to do it but it just falls flat.
There is always the nostalgia factor so maybe 10 years from now, the ST will be looked back upon as "underrated" and "overhated" by people who grew up with the films (which seems to be the case for PT and the Amazing Spider-man series) but this really is nostalgia googles. The PT was not a good trilogy with an interesting story that was poorly executed as was ASM.
