I saw the movie tonight at the local AMC Theatre at 7pm. There was pretty good-sized crowd; Some adults with Power Rangers shirts, and a little kid dressed as the Red Dino Charge Ranger. I wore my newest Power Morphicon shirt.
It's best going into the movie dropping what you already know about all of the characters from the series. They're vaguely similar, but their personalities, backstories, and such are quite different. You will spend a decent amount of time learning about them and their problems. My "review" here will mostly go over what I liked and didn't like as a Power Rangers fan, I'm certainly no film critic. Spoilers ahead.
The movie begins with an ancient battle on Earth, with a dying Zordon (Bryan Cranston, as the original Red Power Ranger) battling Rita Repulsa (Elizabeth Banks). There seems to be an awful lot going on, such as attacking spaceships, but no real explanation is given, so hopefully that will be expanded upon in prospective sequels. The Zeo Crystal is quick to be mentioned, and becomes an important element of the plot, but from the sound of it, it's role, power, and design are much different than that of the series.
The title screen is a simple plain text in the lower right hand corner. Personally, I like flashy title logos. Gone is the Command Center as a building; it's replaced with a spaceship of some type (like the one at the beginning?) buried underground. Alpha 5 has a new, unique design, I would compare it slightly to the Millennian from GODZILLA 2000. Voiced by Bill Hader, he provides some dry humor; Personally I was surprised, as I thought they'd be pushing him as some sort of goofy, idiot comic relief character to get a few laughs from the kids. At one point we get his classic "Aye yai yai" line.
That said, while this IS a film kids can watch, it is rated PG-13, and definitely goes far beyond anything the show has ever done. Numerous references to killing, actual deaths, several uses of "ass" and "shit", and an almost-use of the f-bomb. Sexting and drug use are also alluded to, as well as the (off-screen) unintentional pleasuring of a bull (seriously).
The suits look a bit better in action than the initial images that were released. I think they could have done a better job with making the helmets each look a bit more unique. The only weapon shown is the Red Ranger's sword, no other weapons, even the Blade Blasters, seem to be present.
As a huge fan of Power Rangers villains, I was reasonably disappointed in the villain designs. Rita bears little resemblance to her original counterpart, sporting a largely green-armored design, and with good reason, she's the original Green Ranger (though appears only briefly with the helmet early in the film). Her staff, bearing only the vaguest of similarities to the original, is made of the gold she collects, with the Green Power Coin held within the crescent portion. Rita is portrayed effectively scary, many of her scenes have a good horror vibe to them, and she kills and/or seriously wounds several people. There's one scene that was extremely similar to one from LEPRECHAUN 2 where she does a little gold digging from a homeless guy.
In the film itself, the "Go Go Power Rangers" theme is briefly used when the zords go on the march. The version used is the one from the original movie, interestingly (they also appear to drown out the "Mighty Morphin" part). A new, instrumental version is included as part of the credits. There's also a godawful new cover of Snap!'s song "The Power" at the first of the credits.
The movie ends with Rita being defeated in a fashion where they could either decare her dead, or easily bring her back. Interesting the whole space dumpster aspect is never used, she simply spent millions of years in dormancy under the sea (and conveniently recovered by fishermen at the same time the Rangers find the Coins...).
With all of the redesigns and personality changes, there ARE a couple references for the longtime fans. Jason David Frank and Amy Jo Johnson get cameos at the end of the movie, in the crowd celebrating the Megazord's victory, everyone taking selfies. If one wanted to assume they're a couple, this is good vindication for fans who were pro Tommy x Kimberly, that's at least in some alternate continuity they ended up together. And when Jason's dad is driving around looking for his son, he mentions the locations of Mariner Bay and Reefside. This will go unnoticed to the casual viewer, but these were also names of the cities in POWER RANGERS LIGHTSPEED RESCUE and DINOTHUNDER, respectively.
I went into the movie expecting to be disappointed, but I can't say I was. They took many liberties with the source material, but in a way made it something new entirely. The mid-credits scene gives a set-up for a possible (and intended) sequel, but I won't ruin it (and sadly, it doesn't involve Lord Zedd). I guess we'll just see how well it does, though there have been plenty of sequels to films that were essentially flops.
It will never beat the original, but I think it was fair.
