In Another World With My Smartphone

Skip this preface if you want to get straight to the review

Now to the scoring system

First of all, if you want any originality you're wrong here.
If you like crappy powerfantasy Isekai then this is the right Anime for you. This is probably everything you'll need to know from this review to decide if you want to watch this show.

-I'm into crappy powerfantasy Isekai-

Premise
One day our protagonist wakes up and sees an old man.
This man is god and he apparently made a mistake and let a thunder kill our protagonist.
As an excuse he gets reincarnated into a magic world with busted abilities and his phone, also with busted abilities.
The story continues with him showing his strength and building a harem out of underaged, but marriable, girls.

Characters

Protagonist
We have the MC. He's a very avarage guy.
I can't describe him further just because of how average he is. Of course he also lacks the common sense to see that his harem loves him.
This averageness makes him boring as a character, but likable as a crappy protagonist as he's kind and feels a bit familiar.

Harem Squad

1. The shy twin.
2. Her sister, the tsundere girl.
3. The traveling katana wielding but still girlish girl which misses her family.
4. The princess who's open for polygamy and is almost as average as the protagonist aside from that.

Supporting characters
I won't get into details with that as they are multiple supporting characters each being introduced in separate parts of the story.

Know that they are all pretty generic but most of them are pretty likable.
Their characters are simple but they do all have common traits which are enjoyable to watch and a bit healing.
Overall I liked almost all the characters but will never look back to any of these character.

Plot
I described the plot in the summary.
There is no goal of the MC and no path he follows.
Each episode introduces another topic and includes a few characters we know.

There's also one topic of the latter episodes which technically was part of the story over multiple episodes but 90% of the topic was dealt with in one episode.
This is a spoiler for this episode

Music & Animation
I wasn't particularly a fan of eather of them but they're fine. Probably both below average but nonetheless easily acceptable.

Other things worth mentioning
No, this title is a very generic powerfantasy Isekai.
That's the reason I watched it and enjoyed it. It was overall okay as it was what I wanted. I won't remember it however as there was no point my expectation were exceeded which they are in other generic shows, even if only for a couple minutes.
I think and hope that this shows how generic this show really is.
It's really generic.

TL;DR:
If you want any originality you're wrong here.
If you like crappy powerfantasy Isekai then this is the right Anime for you.

I also found out that my English is trash but that is ignorable.]
