With regards to the lightsaber, even the original was impractical because it had no hilt at all. Swords have hilts to protect the wielder's hands. I'm having trouble thinking of a sword design that doesn't have some form of hilt. The closest I can think of is Japanese sword designs which have a small disk as a hilt instead of the cross shape used in European designs.
Also the idea of a melee weapon in a futuristic age is impractical. Sure they can deflect "some" shots at them but as is often shown with the "extras" the Jedi still can get mowed down by lots of shoots because they are arrogantly over confident by not taking cover.
Then their is the basic issue of actually engaging in lightsaber combat as was already discussed in length by the fan after the Yoda fight scene. Thing like a taller opponent has greater reach which gives a distinct advantage in melee combat. Or races like the ones with the tentacles for hair would need to be extra careful given all the flipping could result in some getting cut off with a mis-swing.
And that doesn't even get into the sheer lack of science regarding their functioning. The closest speculation on how they might actually work is a plasma stream contained in magnetic field. But even that poses problems because they wouldn't be solid like we see when two collide. In order to cut through things as easily as it does it would have to heat the plasma stream so hot that you could see the heat coming off it and would easily burn things by proximity alone.
So the argument of the impracticality of a new design for a weapon that itself is impractical is kinda pointless. It all really only comes down to if you like the design or not.
Now on the topic of feathered dinosaurs I think the ones show in the video looked stupid and far less threatening than the ones in the original Jurassic Park. However I'm not appose to the idea of feather dinos. The problem with the ones shown is they are all rainbow colored which just looks stupid and begs the question how does that allow them an evolutionary advantage? Some modern birds can afford the vibrant multi-colors because they have few predators, flight, and it's for attracting a mate.
But it seems like far more birds have only one or two solid colors, usually in a darker such as brown so they can blend in with their surroundings. This can apply to predators trying to sneak up on their prey just as much as it applies to pray trying not to get caught. But a giant multi-colored T-Rex is gonna stick out like a sore thumb and it's pray would see if coming a mile away. Even cheetahs which as extremely fast try to sneak up as close as they can to their pray before going in to save energy.
So in short if they do it right I think feathered dinos could work. But not of that raindow crap. And they will have to get past nearly a century of the old reptile model of dinos that is the common public perception. I know some said public views on that we shifting but I haven't really seen it. My nephew is into dinos and among his toys, cloths, and etc I see nothing but the reptile style dinos and not a single feathered one. While I have often heard the Dinos turned into birds both in school and in the previous Jurassic Park movies they make mention of it. I haven't really seen many depictions of feathered dinosaurs.
In the end I say let academia and the scientific community do it's thing and just let Hollywood do it's thing with the monster movies. Because the Dinosaurs in those movies are genetic monsters created with incomplete DNA and the gaps filled in. Regardless of how much they try to pretend it's based on real science it's not, otherwise we would already have a real life dinosaur by now. It about as scientific as King Kong, Rise of Planet of the Apes, Jaws Series, Godzilla, and any other number of nature turned monster stories they all can be picked apart by glaring inaccuracies of real science.
Which is why they are Fictional movies and not "Based on Real Events" because reality if very dull where none of those things are even remotely possible given our current technology and most likely never will be because they are impossible. All that matters is was it fun to watch because Hollywood is in the business of making entertainment.
