I've been watching Brony Curious' videos such as Luna the Dreamwalker and he brought up some interesting points. Now, i do love mlp but i see a few problems with some plots.
1. Mlp fim season 1 ep. 1 and 2:
Why did it take 1000 years and why banish luna if the elements of harmony freed her right away when the mane 6 used them on her?
2. Apple Family Reunion:
Granny Smith says the reunion is every 100 moons (8 years) yet in one reunion photo we see applejack, applebloom and big mac all the same age and not little.
Also in S1E4 Applejack says the ponies that Twilight met in episode 1 were there for THE reunion. Could It have been 8 years already since twilight's arrival or is it just a writers goof?
3. Dreamwalker Luna- this isn't really a plot hole, however, could it be that nopony remembered her advice in their dreams if she had this power pre- Nightmare Moon? And therefore felt that she got no recognition in that sense either? Or it could just be that she was given this job after her return to make her feel more useful.
Please tell me what you think/if you found more plot holes. And again, i love this show, but i noticed some problems in some episodes. That said, i hope S4 gives me some answers!
