Если (ModelState.IsValid == false) return View(); или View (model);?

Когда проверка не удалась, какой из них я должен вернуть? Посмотреть(); или вид (модель);

Я замечаю, что оба работают. Это запутанно.

EDIT:

public class MoviesController : Controller
{
    MoviesEntities db = new MoviesEntities();

    //
    // GET: /Movies/

    public ActionResult Index()
    {
        var movies = from m in db.Movies
                     select m;
        return View(movies.ToList());
    }

    public ActionResult Create()
    {
        return View();
    }

    [HttpPost]
    public ActionResult Create(Movie movie)
    {
        if (ModelState.IsValid)
        {
            db.AddToMovies(movie);
            db.SaveChanges();

            return RedirectToAction("Index");
        }
        else
            return View();//View(movie);
    }
}

My Create.aspx:

<% using (Html.BeginForm()) {%>
    <%: Html.ValidationSummary(true) %>

    <fieldset>
        <legend>Fields</legend>


        <div class="editor-label">
            <%: Html.LabelFor(model => model.Title) %>
        </div>
        <div class="editor-field">
            <%: Html.TextBoxFor(model => model.Title) %>
            <%: Html.ValidationMessageFor(model => model.Title) %>
        </div>

        <div class="editor-label">
            <%: Html.LabelFor(model => model.ReleaseDate) %>
        </div>
        <div class="editor-field">
            <%: Html.TextBoxFor(model => model.ReleaseDate) %>
            <%: Html.ValidationMessageFor(model => model.ReleaseDate) %>
        </div>

        <div class="editor-label">
            <%: Html.LabelFor(model => model.Genre) %>
        </div>
        <div class="editor-field">
            <%: Html.TextBoxFor(model => model.Genre) %>
            <%: Html.ValidationMessageFor(model => model.Genre) %>
        </div>

        <div class="editor-label">
            <%: Html.LabelFor(model => model.Price) %>
        </div>
        <div class="editor-field">
            <%: Html.TextBoxFor(model => model.Price) %>
            <%: Html.ValidationMessageFor(model => model.Price) %>
        </div>

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>

<% } %>

<div>
    <%: Html.ActionLink("Back to List", "Index") %>
</div>
