First off, 3 of the originals were fired cuz of this film. That last song isn't like it either.
Heck, few of the songs are done by Ron Wasserman.
Tommy doesn't go on Martial Arts tournaments.
Rocky doesn't play as his second in command.
Adam doesn't get the notable well written episodes he normally gets.
Kimberly doesn't do the valley girl gymnastics thing combined with other notable out of valley girl stuff that made her stand out in the first season.
Billy doesn't do any nerdy stuff.
They don't go to school.
They're not even on summer vacation.
Bulk and Skull don't try and unmask the Power Rangers or act like bullies like in the first two seasons.
There's no Ernie, Kaplan or Appleby.
Both Power Rangers film Fox originals have kids in them wanting to be or are Power Rangers.
Ivan Ooze's Ooze makes people want to buy more Ooze, the very reason that gave Haim Saban power and got the 3 Ranger actors fired.
The Megazords are made out of cheap $10 million 3D opposed to the $100 million 3D of T2 and Pacific Rim.
There's very little character writing in this movie, which is all what we adore and which is critical in a film that is non-canon.
