You’re good at making them after you've come up with the idea, but you are terrible at coming up with good ideas.

I wish I was extremely great at coding, in every coding language.

As long as nobody ever twists my wish, sure, granted.

I wish that someone would reply to my post.

Someone replied to your post and insults you

I wish I could fly

You get polymorphed into a fly, you die in 24 hours.

I wish I was a lot smarter.

You are a lot smarter. Unfortunately, as previously said, you didn't give a quantity.

I wish I knew if films were good or bad before I went to see them. (Independent of Rotten Tomatoes etc.)

(”Lot” definition: a large number or amount; a great deal. How is that not an amount? It may not be exact, but it still is clear how much smarter I should become)

But only after buying the ticket, still technically before you see it.

I wish for two (2) more wishes.

2

 Ouch, you make your wish for more wishes, but since it was a nonstandard wish, you had a 1/3 chance of never being able to cast it again. You would have been safe on a 1 or 2, but alas, you got a 3 and can never cast Wish again.

I wish that I never suffered the negative effects of allergies. 

Because you don’t have a mouth, nose, or skin.

I wish I was holding a wrapped, un-melted, edible chocolate bar

Wish granted! Said chocolate bar appears in your hand! You lift it to your mouth to take that first sweet bite, only to find... your tongue is gone and you will never taste chocolate again.

I wish I had the DM skill of Matt Mercer.

Granted, you are now decent at Direct Messaging people!

I wish I could download and install mods faster, for any and all games.

Granted! You can now download and install mods faster for any and all games. Sadly you don't own any of the games.

I wish that everyone else can have their wish come true.

Granted, everyone else has their wish come true, but you’re not ’everyone else’, so your wish doesn't come true, so no one elses wishes come true. You just did sweet nothing, good job.

I wish I had a perfect sleep schedule that could never be broken.

You get a perfect sleep schedule for a tiger shark

I wish a won the lottery 

There's no such thing ”the lottery” only various ”a lottery”s, so you win nothing ;(

I wish I could control my skill level at all games, For example: I could be very bad at a certain game, but incredible at another, if I so desired.

Granted, you already possess these powers, it's called practice and atrophy.

I wish I was fluent in every language on earth that is spoken by more than one million people.

Granted, You are fluent in many, many languages, sadly, because your brain is so overloaded with information about all the different languages, you have memory loss and can only remember up to about 10 seconds ago.

I wish I was significantly better at finding specific bits of media that I enjoy.

Wish granted however you can only watch a small bit of that media (2 to 3 seconds)

I wish that I could never get stuck in traffic. 

Granted. You are now unable to be in a vehicle.

I wish I was 1.5 times better at rhythm games

Granted, but 1.5 times zero is still zero.

I wish I could use wild shape.
