código web.php:

<?php

/* |-------------------------------------------------------------------------- | Web Routes |-------------------------------------------------------------------------- | | Here is where you can register web routes for your application. These | routes are loaded by the RouteServiceProvider within a group which | contains the "web" middleware group. Now create something great! | */ Route::get('/series', 'SeriesController@index');

código SeriesController

<?php

namespace App\Http\Controllers;


class SeriesController extends Controller
{
    public function index() {
        $series = [
            'Grey\'s Anatomy',
            'Lost',
            'Agents of SHIELD'
        ];

        $html = "<ul>";
        foreach ($series as $serie) {
            $html .= "<li>$serie</li>";
        }
        $html .= "</ul>";

        return $html;
    }
}

Desculpa galera eu sei que a resposta eu sei que a resposta veio logo em seguida mas eu continuei pesquisando aqui e consegui resolver o problema com essa sintaxe aqui:

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\SeriesController;



Route::get('series',[SeriesController::class, 'index']);

Alternativas:

1-
use App\Http\Controllers\SeriesController;
Route::get('series',['SeriesController@index']);
2-
use App\Http\Controllers\SeriesController;
Route::get('series',['\App\Http\Controllers\SeriesController\SeriesController@index']);
3- 
Route::get('series',[\App\Http\Controllers\SeriesControllerSeriesController::class, 'index']);
