MLP "Tale Your Tale" is good but lacks substance. The movie ("A New Generation, aka. ANG) also was lacking in substance, which presents a problem for this new series. Normally shorts don't need much substance, but they are also normally based on a movie, series, or show that has a good amount of substance, so to make a substance-lacking short based on a substance-lacking movie causes issues. These issues are apparent throughout the four currently released shorts in "Tell You Tale" (TYT), and will likely manifest themselves throughout this short series. The issues I'm referring to are lack of worldbuilding, lack of character development, and other areas that have little to no substance.

Examples:

1) Sunny's lighthouse is fully restored in a similar way to The Golden Oak Library. How and when did this restoration occur? We don't know, and this problem is a result of lack of worldbuilding.

2) Izzy is (or was?) a bad roommate. Now what I'm about to say is debatable, but I'm going to say it anyways. I think that Izzy's behavior in ANG does not indicate that she would become a bad roommate. I mean, she was not as hyperactive and careless in ANG as she was in TYT, so where did this behavior come from? We don't know, so this problem is a lack of character development.

3) Hitch has a crab. Nowhere was this crab seen in ANG, so where did it come from and how did Hitch get it as a pet? We don't know, and this constitutes as lack of worldbuilding and character development due to the fact that Hitch's relationship with the crab wasn't developed at all before TYT was released.

4) Izzy was able to simultaneously sleep and cast a spell that levitated and moved Pipp's blanket. How was she able to do that? We don't know, so again this is an example of lack of worldbuilding.

Those are a few examples that I listed, but there are probably more that I am not aware of as of now, since I only watched each episode once so far. My point in listing those examples, regardless of whether or not they are legitimate, is to solidify my point that lack of substance in shorts that are based on a substance-lacking movie leads to lack of worldbuilding and lack of character development and that leads to issues such as those provided above.
