Which movie should I watch?

Borrowed a couple of DVDs and wanted to know which would cheer me up most (none of them are comedies as far as I can tell).

1. Agnieska Holland’s “Total Eclipse” with L.Di Caprio

2. Federico Fellini’s “La Dolce Vita” with M.Mastroianni

3. Jim Jarmusch’s “Welcome To Florida” (or at least that’s what I think it’s called) from 1984.

Jarmusch is my favourite, but the particular film could be depressing, and I’m looking for something to cheer me up.
